Toyota Hilux DPF Problems: Causes, Symptoms, Fixes, and Prevention

The Toyota Hilux has earned its reputation by doing the sort of work that makes softer vehicles nervous. It hauls trailers, crawls over rough tracks, spends hours on worksites, and regularly survives conditions that would make an ordinary crossover beg for retirement. Yet even a famously tough ute can have one part that causes headaches, and on some diesel Hilux models, that part is the diesel particulate filter, better known as the DPF.

Toyota Hilux DPF problems can range from an annoying warning light to repeated regeneration cycles, reduced engine power, excessive fuel consumption, or a filter so restricted that professional cleaning or replacement becomes necessary.

The frustrating part? A DPF problem does not automatically mean the DPF itself is defective.

Sometimes the filter is simply overloaded with soot. Sometimes the engine is producing too much particulate matter. In other cases, a sensor, injector, exhaust component, driving pattern, or failed regeneration is hiding behind the warning message.

So, rather than treating the DPF like the villain of the story, we need to understand the complete system.

In this guide, we'll explore the most common Toyota Hilux DPF problems, the symptoms worth watching, why regeneration sometimes fails, what owners can do about it, and how we can reduce the chances of the issue returning.

What Is the DPF on a Toyota Hilux?

A diesel particulate filter is fitted within the exhaust system of many modern diesel vehicles. Its purpose is simple in theory: capture microscopic soot particles before they leave the exhaust pipe.

Imagine the DPF as a very sophisticated chimney filter.

Diesel combustion naturally creates particulate matter. Instead of allowing much of that soot to escape directly into the atmosphere, the filter traps it inside a porous ceramic structure.

Eventually, however, the captured soot needs somewhere to go.

That's where regeneration comes in.

During regeneration, exhaust temperatures rise sufficiently to burn accumulated soot and convert much of it into a smaller amount of ash.

The cycle looks roughly like this:

Diesel combustion → soot production → soot trapped in DPF → regeneration → soot burned → residual ash remains

When everything works properly, the driver may barely notice the process.

When regeneration repeatedly fails, trouble begins.

Which Toyota Hilux Models Can Experience DPF Problems?

DPF systems are associated mainly with later diesel Hilux generations designed to comply with increasingly strict emissions standards.

Exact hardware, software, regeneration strategies, warning lights, and driver-operated regeneration functions can vary considerably according to:

• Model year
• Engine
• Transmission
• Emissions specification
• Country
• Vehicle software calibration
• Commercial or private-market configuration

For that reason, we should never assume that instructions applying to one Hilux automatically apply to another.

The vehicle owner's manual remains the best reference for model-specific warning lights and regeneration procedures.

The 2.8-Litre Diesel Hilux Gets Much of the Attention

Many discussions surrounding Toyota Hilux DPF problems involve vehicles equipped with Toyota's modern 2.8-litre turbo-diesel engine.

That does not mean every 2.8 Hilux develops DPF trouble.

Far from it.

Thousands operate normally.

However, vehicles that regularly experience conditions unfavourable to regeneration can be considerably more vulnerable to soot accumulation.

How Does Toyota Hilux DPF Regeneration Work?

For the DPF to continue capturing soot, it periodically needs to clean itself.

This process is known as DPF regeneration.

There are several ways regeneration can occur.

Passive Regeneration

Passive regeneration happens naturally when exhaust gas remains hot enough for long enough to oxidise soot.

Think motorway driving, sustained highway speeds, towing, or longer journeys where the engine reaches normal operating temperature.

Under the right conditions, the filter quietly cleans itself without the driver doing anything.

Active Regeneration

Normal driving doesn't always create enough heat.

When the engine control system determines that the DPF has accumulated a certain quantity of soot, it can deliberately increase exhaust temperature.

Depending on the engine and emissions strategy, this may involve changing injection timing or using additional fuel to help create the heat required for regeneration.

Drivers may notice:

• A slightly elevated idle
• A temporary increase in fuel consumption
• Cooling fans operating
• A different exhaust smell
• Slightly altered engine behaviour

These signs aren't automatically a problem.

They may simply mean the Hilux is regenerating.

Manual or Forced Regeneration

Some Hilux configurations provide a driver-controlled DPF regeneration function, while workshop diagnostic equipment can initiate a forced regeneration under appropriate circumstances.

We should distinguish the two.

A driver-initiated regeneration must follow the exact procedure specified for the vehicle.

A workshop forced regeneration is a diagnostic/service procedure and shouldn't be treated as an automatic cure for every DPF warning.

If there is a mechanical fault causing excessive soot production, burning the soot away without solving the underlying problem can simply restart the cycle.

Common Toyota Hilux DPF Problems

Although owners often describe almost everything as a "DPF problem," several different failures can create similar symptoms.

The most common scenarios include:

1. Excessive soot accumulation
2. Incomplete regeneration
3. Frequent regeneration cycles
4. DPF warning lights
5. Loss of engine performance
6. Faulty pressure or temperature sensors
7. Excessive ash accumulation
8. Injector or combustion-related issues
9. Regeneration interrupted by driving conditions
10. Engine oil contamination associated with repeated regeneration attempts

Understanding which situation we're dealing with is far more useful than simply replacing parts.

Toyota Hilux DPF Warning Light: What Does It Mean?

A DPF-related warning usually means the vehicle has detected an abnormal level of particulate accumulation or another fault affecting the emissions system.

It shouldn't automatically trigger panic.

But it shouldn't be ignored either.

A warning can represent different levels of urgency depending on whether it appears alone or alongside other indicators.

DPF Light Appears Without Other Warning Lights

In some circumstances, this can indicate that the filter requires regeneration.

The correct response depends on the Hilux model.

Some versions may allow regeneration through an appropriate driving cycle. Others may provide a manual regeneration procedure.

We should follow the owner's manual rather than relying on generic internet advice.

DPF Light Plus Check Engine Light

The situation becomes more serious when multiple warnings appear simultaneously.

There may be:

• Excessive filter restriction
• Failed regeneration
• Exhaust temperature sensor trouble
• Differential pressure sensor problems
• Fuel injection faults
• EGR-related problems
• Airflow or boost issues
• Stored emissions-system diagnostic codes

At this stage, blindly driving at motorway speed in the hope that the problem disappears isn't a particularly clever strategy.

Proper diagnosis becomes important.

Symptoms of a Blocked Toyota Hilux DPF

A restricted DPF can behave like someone gradually pinching the exhaust system closed.

The engine needs to breathe both in and out. Excessive exhaust backpressure can interfere with normal operation.

Typical signs include:

• DPF warning light
• Check engine light
• Reduced engine power
• Sluggish acceleration
• Increased fuel consumption
• More frequent regeneration
• Strong exhaust smell
• High idle during repeated regeneration
• Engine entering limp mode
• Increased cooling-fan activity
• Regeneration failing to complete

Some symptoms overlap with turbocharger, EGR, airflow, injector, and fuel-system faults, which is why diagnosis matters.

Why Does a Toyota Hilux DPF Become Blocked?

The simplest explanation is:

The engine produces soot faster than the vehicle can successfully remove it.

But why would that happen?

There are several possibilities.

Short Trips Are a Major DPF Enemy

Diesel engines with particulate filters aren't particularly fond of repeated five-minute journeys.

Imagine starting the Hilux, driving to the shops, switching it off, starting again later, and repeating the pattern every day.

The engine may barely reach full operating temperature.

Exhaust temperature remains relatively low.

Regeneration opportunities become limited.

If an active regeneration starts just before we reach our destination and we switch the engine off, the process may be interrupted.

Do that repeatedly and soot accumulation can steadily increase.

City Driving Can Make the Problem Worse

Stop-start urban traffic creates similar conditions.

Low engine load and short driving cycles don't always generate the sustained exhaust heat needed for effective regeneration.

That doesn't mean diesel Hilux models cannot be driven in cities.

It simply means a vehicle used almost exclusively for low-speed, short-distance driving may face tougher DPF operating conditions than one regularly covering longer journeys.

Interrupted Regeneration Can Cause Trouble

Imagine washing a muddy Hilux but turning off the hose halfway through every time.

Eventually, the dirt wins.

Regeneration is similar.

If the system repeatedly begins the process but cannot complete it, the soot load can continue rising.

Potential reasons include:

• Switching the engine off
• Driving only very short distances
• Insufficient exhaust temperature
• Fuel level being too low on some vehicles
• Existing engine faults
• Sensor problems
• Abnormal combustion
• Regeneration being inhibited by a stored fault

One interrupted regeneration isn't usually catastrophic.

Repeated interruptions are more concerning.

Frequent Toyota Hilux DPF Regeneration

What if regeneration seems to happen constantly?

That deserves investigation.

A healthy DPF will regenerate periodically, but extremely frequent regeneration may suggest the system is accumulating soot unusually quickly or incorrectly calculating soot load.

Potential causes include:

• Mostly short-distance driving
• Excessive engine soot
• EGR problems
• Injector issues
• Intake restrictions
• Boost leaks
• Incorrect sensor readings
• Differential pressure sensor faults
• DPF nearing its ash capacity
• Failed previous regenerations

The regeneration frequency alone does not identify the faulty component.

It gives us a clue.

DPF Soot and DPF Ash Are Not the Same Thing

This distinction is one of the most important points in understanding Toyota Hilux DPF problems.

Soot Can Usually Be Burned

Soot is a carbon-rich material created during combustion.

Regeneration burns much of it away.

Ash Cannot Be Regenerated Away

Ash consists largely of non-combustible residue.

Over a long enough period, ash gradually accumulates inside the filter.

Regeneration doesn't make it disappear.

That's why an older, high-mileage DPF can eventually require specialised cleaning or replacement even if regeneration has always worked correctly.

Think of It Like a Fireplace

We can burn logs and make the wood disappear.

But we're still left with ash.

Eventually, someone needs to empty the fireplace.

The DPF follows a similar principle.

Toyota Hilux DPF Differential Pressure Sensor Problems

The engine control system needs to estimate how restricted the DPF is.

One important tool is the differential pressure sensor.

It compares exhaust pressure before and after the filter.

As restriction increases, the pressure difference normally increases.

If the sensor itself fails—or if its pressure hoses become damaged, blocked, cracked, or contaminated—the control unit may receive incorrect information.

That can lead to strange behaviour such as:

• Incorrect DPF warnings
• Regeneration happening too frequently
• Regeneration failing to initiate
• Fault codes
• Limp mode
• Implausible soot-load readings

This is why replacing the entire DPF without testing supporting sensors can become a very expensive guessing game.

Exhaust Temperature Sensors Can Affect Regeneration

Regeneration depends heavily on exhaust temperature.

The ECU needs to know whether the exhaust is hot enough and whether temperature remains within acceptable limits.

If an exhaust gas temperature sensor provides implausible information, regeneration strategy can be disrupted.

A faulty temperature sensor might make the ECU believe that:

• The exhaust is too cold
• Regeneration isn't working
• Exhaust temperature is dangerously high
• Regeneration conditions haven't been satisfied

Again, a DPF warning does not necessarily mean a defective filter.

Fuel Injector Problems and DPF Blockage

Injectors play an enormous role in diesel combustion.

If fuel delivery becomes inaccurate, incomplete combustion can generate excessive particulate matter.

Symptoms may include:

• Rough running
• Diesel knock
• Smoke
• Poor economy
• Hard starting
• Increased soot production
• Repeated DPF regeneration

Now the DPF becomes the messenger rather than the offender.

It is simply catching the soot created elsewhere.

Cleaning or replacing the filter without fixing the combustion problem is like emptying a bucket while leaving the tap running.

Can the EGR System Cause Toyota Hilux DPF Problems?

Potentially, yes.

The exhaust gas recirculation system helps reduce nitrogen-oxide emissions by routing a controlled amount of exhaust gas back into the intake.

Over time, diesel EGR and intake systems can accumulate carbon deposits.

If EGR operation becomes abnormal, the engine's air-fuel environment can change and soot production may increase.

Possible related symptoms include:

• Poor throttle response
• Rough running
• Reduced power
• Increased soot accumulation
• Check engine light
• Abnormally frequent DPF regeneration

However, we shouldn't automatically blame the EGR every time the DPF light appears.

Diagnosis should come first.

Toyota Hilux DPF and Limp Mode

If the engine management system detects excessive DPF restriction or another serious emissions-system fault, it may limit performance.

This is commonly called limp mode.

The truck can feel as though someone has removed half its confidence.

Acceleration becomes weak and engine output may be restricted.

The purpose is protective.

Continuing to demand full performance when exhaust restriction is excessive could increase thermal and mechanical stress.

Should We Keep Driving in Limp Mode?

Not as normal.

If the Hilux enters limp mode alongside emissions or engine warnings, we should arrange proper diagnosis rather than continuing to drive it hard.

A severely overloaded DPF may not be suitable for an ordinary regeneration attempt.

Can Highway Driving Clear a Hilux DPF?

Sometimes—but this advice is far too often oversimplified.

You've probably heard something like:

"Take it on the highway and drive it hard."

There is a grain of truth behind the idea.

Longer journeys at normal operating temperature can create favourable regeneration conditions.

But highway driving isn't a magical cure.

If the DPF is excessively restricted or regeneration is being prevented by another fault, motorway driving may accomplish nothing.

The right approach is:

• Follow Toyota's instructions for the exact model.
• Do not intentionally drive aggressively.
• Never attempt to "burn it clean" when serious warning lights, abnormal noises, overheating, or limp mode suggest a larger issue.
• Diagnose recurring warnings rather than repeatedly forcing regeneration.

How to Perform a Toyota Hilux DPF Regeneration

There is no single regeneration procedure that safely applies to every Hilux.

That's important.

Some vehicles rely primarily on automatic regeneration. Certain configurations may include a regeneration switch or specific driver procedure.

Therefore, the safest sequence is:

1. Confirm the exact model, engine, and year.
2. Read the DPF section of the owner's manual.
3. Make sure no warnings indicate that regeneration should not be attempted.
4. Park or drive only under the conditions Toyota specifies.
5. Allow the process to complete.
6. Seek diagnosis if the warning returns.

Never Regenerate Near Flammable Material

DPF regeneration creates extremely high exhaust temperatures.

Avoid dry grass, leaves, fuel, oil, paper, or other combustible material around the exhaust.

This matters especially for Hilux owners working on farms, construction sites, forestry areas, or dry off-road terrain.

Why Does the Toyota Hilux DPF Light Keep Coming Back?

A warning that disappears after regeneration but repeatedly returns may reveal something more important.

The regeneration may be treating the symptom rather than the cause.

Common possibilities include:

• Excessively short driving cycles
• High soot production
• Sensor faults
• Injector problems
• EGR issues
• Intake or boost leaks
• Thermostat or engine-temperature problems
• Excessive ash load
• Software/calibration issues
• DPF damage

If regeneration becomes a weekly ritual, we shouldn't simply accept it as normal.

Find out why.

How Mechanics Diagnose Hilux DPF Problems

Good diagnosis is more sophisticated than reading one fault code and ordering a filter.

A technician may examine:

• Stored diagnostic trouble codes
• Live DPF differential pressure
• Calculated soot loading
• Exhaust temperature readings
• Regeneration history
• Distance since previous regeneration
• Injector correction values
• Mass airflow readings
• Boost pressure
• EGR operation
• Engine temperature
• Pressure-sensor hoses
• Oil level and condition

The DPF itself may also need physical inspection.

Live Data Can Tell a Story

Diagnostic data becomes particularly valuable when readings are compared under different engine speeds and loads.

For example, unexpectedly high differential pressure with a relatively low calculated soot load could point the investigation in a different direction from a vehicle showing genuine excessive particulate accumulation.

That is why experienced diagnosis saves money.

Can a Toyota Hilux DPF Be Cleaned?

Often, yes.

The correct cleaning method depends on what is actually blocking the filter.

Regeneration for Soot

If soot load remains within a safe range, controlled regeneration may restore normal operation.

Professional Off-Car Cleaning

When ash is the problem, the DPF can sometimes be removed and cleaned using specialist equipment.

Professional cleaning may involve controlled airflow, liquids, heat, or combinations of processes designed specifically for particulate filters.

The cleaned filter should ideally be tested for airflow or backpressure before being reinstalled.

When Cleaning Won't Save It

Replacement can become necessary when the DPF is:

• Cracked
• Melted
• Internally damaged
• Contaminated beyond recovery
• Physically deteriorated
• Unable to achieve acceptable flow after cleaning

A replacement DPF installed without identifying the cause of the original failure can suffer the same fate.

Toyota Hilux DPF Replacement Cost

There is no useful universal figure because costs vary dramatically by location, Hilux generation, engine, genuine-versus-aftermarket components, labour rates, and whether sensors or associated repairs are also required.

The overall bill may include:

• Diagnostic labour
• DPF removal
• Professional cleaning
• Replacement DPF
• Gaskets and fittings
• Exhaust sensors
• Pressure hoses
• ECU procedures
• Oil and filter service
• Injector or EGR repairs

Before approving an expensive DPF replacement, asking for supporting diagnostic evidence is perfectly reasonable.

Can DPF Problems Increase Fuel Consumption?

Yes.

Repeated active regeneration can use additional fuel.

A partially restricted exhaust can also reduce engine efficiency.

We may notice the Hilux visiting the fuel station more frequently even though driving habits haven't changed.

An unexplained increase in fuel consumption combined with frequent regeneration deserves investigation.

Can DPF Regeneration Affect Engine Oil?

Repeated unsuccessful regeneration attempts can sometimes contribute to engine-oil dilution on diesel engines.

Depending on the engine's regeneration strategy, additional fuel introduced during the process may not always burn completely.

A small amount can reach the crankcase.

Warning signs worth taking seriously include:

• Oil level rising unexpectedly
• Oil smelling strongly of diesel
• Repeated failed regeneration
• Oil-condition warnings where fitted

If the oil level rises beyond the specified maximum, don't simply drain a little and continue indefinitely.

We need to understand why it happened.

Is DPF Delete a Good Solution?

For a road-going Hilux, removing or disabling emissions equipment is generally a poor solution and may be illegal depending on the jurisdiction.

DPF deletion can also create:

• Emissions-compliance problems
• Inspection failures
• Warranty complications
• ECU calibration issues
• Resale difficulties
• Insurance implications

More importantly, deleting the filter ignores the possibility that another engine fault caused the DPF problem in the first place.

Fixing the system properly is the smarter long-term approach.

How to Prevent Toyota Hilux DPF Problems

No routine can guarantee that a DPF will never require attention, but good habits can significantly improve its chances.

1. Give the Engine Proper Longer Runs

If the vehicle spends most of its life on short trips, periodically giving it a sustained normal drive can help provide conditions favourable for regeneration.

2. Avoid Repeatedly Interrupting Regeneration

If we recognise that regeneration is underway and circumstances allow, avoiding an immediate shutdown may help the cycle finish.

Always prioritise safe driving and model-specific manufacturer guidance.

3. Use the Correct Engine Oil

Modern emissions systems often require oil meeting specific low-ash standards.

Using the wrong oil can contribute to unnecessary ash accumulation.

Follow Toyota's exact specification.

4. Fix Engine Problems Early

A small boost leak, injector issue, temperature fault, or EGR problem can eventually become a much larger DPF headache.

5. Maintain the Vehicle Properly

Dirty filters, neglected fluids, incorrect oil, and overdue servicing don't help diesel combustion.

A well-maintained engine generally gives the emissions system an easier life.

6. Don't Ignore Warning Lights

An early warning may represent a relatively manageable soot-loading issue.

Ignore it long enough and the situation can become much more expensive.

Best Driving Habits for a DPF-Equipped Hilux

For everyday ownership, we can keep things simple:

• Allow the engine to reach proper operating temperature regularly.
• Include longer journeys if most daily trips are extremely short.
• Avoid excessive idling where possible.
• Use good-quality fuel from reputable suppliers.
• Keep servicing current.
• Investigate recurring regeneration.
• Use manufacturer-approved oil.
• Address engine warnings quickly.

DPF-equipped diesels generally thrive when used for the sort of sustained driving they were designed to handle.

Is a Hilux With DPF Problems Worth Buying Used?

Potentially—but investigate carefully.

A past DPF problem isn't automatically a reason to reject a vehicle.

What matters is why it happened and whether the underlying cause was repaired.

Before buying, consider:

• Full service history
• Evidence of DPF replacement or cleaning
• Diagnostic scan
• Current DPF pressure readings
• Regeneration history where available
• Engine oil condition
• Injector performance
• Test drive from cold
• Warning lights
• Evidence of emissions-system tampering

A Hilux that has received a properly diagnosed repair may be a far safer purchase than one with no documented history at all.

Be Suspicious of Permanently Hidden Warnings

If warning lights don't illuminate during the ignition self-check, or if emissions-related ECU modifications are suspected, investigate before buying.

The cheapest Hilux can become the most expensive one surprisingly quickly.

Are Toyota Hilux DPF Problems Common Enough to Avoid the Vehicle?

We wouldn't judge the entire Hilux range solely on DPF complaints.

Modern diesel emissions systems are inherently complex, and DPF-related problems are not unique to Toyota.

The more useful question is:

Does the Hilux suit the way we actually drive?

Someone covering long highway distances, towing, or regularly operating the engine at full temperature may have a completely different ownership experience from someone travelling three kilometres through city traffic twice per day.

Vehicle choice matters.

Usage pattern matters too.

Toyota Hilux DPF Problem Checklist

If your Hilux shows a DPF warning, this practical checklist can help organise the next steps:

• Check the owner's manual for the exact warning.
• Note whether additional warning lights are present.
• Observe whether engine power has dropped.
• Check engine oil level.
• Avoid repeatedly clearing fault codes without diagnosis.
• Identify recent driving patterns.
• Determine whether regeneration has been repeatedly interrupted.
• Have diagnostic fault codes scanned.
• Check differential pressure readings.
• Test exhaust temperature sensors if indicated.
• Inspect pressure hoses.
• Evaluate injector performance.
• Check EGR and intake operation where relevant.
• Determine whether soot or ash is causing restriction.
• Repair the root cause before replacing expensive components.

That final point matters most.

Treat the cause, not just the warning light.

The Biggest Mistake Hilux Owners Make With DPF Issues

Probably assuming every DPF warning has the same solution.

One owner may simply need a successful regeneration.

Another may have a failed pressure sensor.

Another could have an injector producing excessive soot.

Another may have a filter full of ash after years of use.

Another could have a damaged DPF that genuinely needs replacement.

The dashboard warning is the beginning of the diagnosis—not the diagnosis itself.

Final Thoughts on Toyota Hilux DPF Problems

Toyota Hilux DPF problems can certainly be frustrating, particularly when a warning light keeps returning after regeneration. But the DPF is part of a much larger emissions and engine-management system, and blaming the filter alone can send us down an expensive rabbit hole.

Start by understanding what the vehicle is telling you.

A simple soot-loading problem caught early may require little more than the correct regeneration procedure. A recurring issue, however, deserves proper investigation of sensors, injectors, EGR operation, engine temperature, airflow, exhaust pressure, driving patterns, and the condition of the filter itself.

The Hilux remains a remarkably capable working vehicle, but even tough machinery appreciates the right operating conditions.

Give the engine regular opportunities to reach proper temperature. Use the correct oil. Don't make a habit of interrupting regeneration. Keep servicing current. And when warning lights appear repeatedly, diagnose the cause instead of endlessly resetting the symptom.

Do that, and the DPF becomes far less mysterious—and much less intimidating.

Frequently Asked Questions

1. Why does my Toyota Hilux DPF light keep coming on?

Repeated warnings usually mean the DPF continues accumulating soot faster than it can remove it, regeneration isn't completing successfully, or another engine or sensor fault is affecting the system. Short trips are one possible reason, but injector, EGR, pressure-sensor, temperature-sensor, airflow, or ash-loading issues should also be considered.

2. Can I drive a Toyota Hilux with the DPF light on?

That depends on the warning state and the specific model. A basic DPF warning may sometimes indicate that regeneration is required, while a DPF warning accompanied by a check-engine light, limp mode, overheating, or severe performance loss warrants professional diagnosis. Follow the instructions in the vehicle's owner's manual.

3. How do I clear a blocked DPF on a Toyota Hilux?

A lightly soot-loaded DPF may recover through an approved regeneration process. More severe restriction may require diagnostic forced regeneration or professional off-car cleaning. A damaged or excessively contaminated filter may require replacement. The root cause of blockage should always be identified first.

4. Does highway driving help clean a Hilux DPF?

Longer journeys at normal operating temperature can provide favourable conditions for regeneration, so highway driving may help in some situations. However, it won't repair failed sensors, injector faults, excessive ash accumulation, or a severely restricted DPF. Never assume high-speed driving is a universal fix.

5. How can we stop Toyota Hilux DPF problems from returning?

Use the correct engine oil, keep servicing up to date, repair engine faults promptly, avoid relying exclusively on extremely short journeys where practical, give regeneration opportunities to complete, and investigate unusually frequent regeneration rather than simply resetting warning lights.
