About This Headlight Control Module
Three different units get sold as a headlight control module, and matching by vehicle alone is how buyers end up wrong. A xenon ballast strikes the arc with a high-voltage pulse - up to 30 kV on later generations - then holds the bulb at 35 W. An LED headlamp needs its own light control unit, usually bolted to the housing: Audi A7 LED variants use a scalable 4, 6 or 8-channel unit driving 32 LEDs in the HD matrix module. An adaptive lighting module is a third thing, reading inputs from around the car and telling the lamps to move up, down or sideways. Match the unit to the technology actually in your housing - one model year is often sold with halogen, xenon and LED. Xenon work is high-voltage work: leave it to a professional.

Before you order, it helps to read:
Common Signs Your Headlight Control Module May Need Replacing
- One headlamp stone dead while the other is normal
- A xenon lamp that tries to strike a few times, then quits
- Flickering, colour-shifted or slow to light on one side
- Adaptive headlights that no longer swivel or brighten in corners
- Auto-levelling stuck high or low, or a levelling warning
- Individual segments dark in a matrix LED lamp while the rest work
Symptoms vary by vehicle and driving conditions. Always confirm diagnosis before replacement.
What to Check When Buying a Used Headlight Control Module
- Identify the unit first - xenon ballast, LED control unit or adaptive lighting module
- Match the lamp technology in your housing - one model is sold with halogen, xenon and LED
- On xenon, check generation - igniters and cables differ in shielding
- On LED, match the variant - channel counts differ inside one model range
- Expect beam aiming at minimum, and ask if yours calls for more
- Hand xenon work to a shop - these fire at tens of thousands of volts
Ask for these details and any available photos before approving a purchase.

We do not display unverified stock records. Send your VIN or year, make, model, and original part number so a specialist can confirm exact fitment and the options currently available.
How Pricing Is Determined
Pricing for used headlight control module depends on several factors:
- Vehicle year, make, model, and engine configuration
- Mileage and overall condition of the donor vehicle
- Supplier location and shipping distance
- Warranty coverage offered
We quote rather than list prices, and on lighting electronics it depends almost entirely on which unit you need. A xenon ballast, an LED control unit and an adaptive lighting module are different parts, and the same vehicle can be built with any of them depending on trim. Tell us what is in the headlamp - xenon bulb, LED module or a lamp that swivels - and send the VIN, because guessing from the model name causes returns. Budget for beam aiming afterwards; whether more is needed depends on the maker and what else was changed.
Confirm the final price and fitment basis before approving a purchase.
Frequently Asked Questions
Does a used headlight control module need calibration or coding?
Careful - this gets over-stated. I-CAR's guidance is that most manufacturers require only headlamp beam aiming when a lamp is installed, and that calibration is required in most cases after replacing the sensors and modules used to operate the headlamps - which is exactly what this part is. Some vehicles also require calibration if suspension parts were removed or replaced. Expect aiming for certain, then check your vehicle-specific service information for whether a calibration applies rather than assuming.
What is the difference between a ballast, an LED driver and an adaptive module?
Job and lamp technology. A ballast serves a xenon bulb: it ignites the gas with a high-voltage pulse, then holds the bulb at a steady power level. An LED control unit serves LED lamps, usually mounted on the housing, switching and dimming individual LEDs. An adaptive lighting module sits above both, taking sensor inputs and commanding the beam to move or change shape. Not interchangeable.
One xenon headlight is out. Is it the bulb or the ballast?
Either, so diagnose before you buy. A faulty ballast causes complete failure of that headlamp. A failing bulb often shows first as repeated ignition attempts, because the ballast has a counting circuit that tries a faulty bulb only seven times before shutting it off. A workshop checks the fuse and supply at the ballast before condemning it. Do not probe it yourself - HID systems run at high enough voltage to cause shock, burns or electrocution.
Can I put a used LED or xenon module on a car built with halogen headlights?
Treat that as a conversion, not a swap. The control unit is one piece: housing, lamps, wiring and, on adaptive systems, the sensors must all belong to the same setup, and retrofits raise road-legality questions that vary by market. Tell us what your car left the factory with and where you want to end up, and we will quote parts that go together.
What is a lighting control module, and does my car even have one?
It is the name for whichever box switches your exterior lights, and it is not always a separate part. NHTSA uses lighting control module as a component category: one campaign covers 2003-2005 Crown Victoria and Grand Marquis cars whose module may fail and cause a loss of headlights, while a 2024-2025 Mustang campaign runs exterior lighting through the body control module.
Low beam, DRL and turn signal are all dead on one side - is that the headlight module?
That pattern points at the lamp's own driver. NHTSA's 2025 Ford campaign describes LED driver modules with a burnt diode causing the low beam, high beam, daytime running light, front position light and front turn signal to fail in the affected headlight - one module, every function on that side. Separate bulbs failing together is far less likely.
Can I fit a matrix or adaptive headlight module from a European-market car?
Assume not. US headlamps are certified to Federal Motor Vehicle Safety Standard 108, which sets its own photometric requirements for adaptive driving beam systems and requires each replaceable-bulb headlamp to be marked with a light-source type recognized under that standard. A European lamp and its control unit are built to a different rulebook.
How is compatibility verified?
Provide your VIN or full vehicle details so you can review the fitment basis in your quote before approving a purchase.
What if the part does not fit?
Most suppliers offer limited return or exchange options. Warranty and return terms are confirmed before purchase.
How long does shipping take?
Shipping time varies by location, part size, and freight arrangement. Confirm the dispatch and delivery estimate in your quote.
