Headlight Computer

The headlight computer — the LED control module behind modern headlamps — decides how the lamp powers up, dims and reports faults. When an aging driver throws errors on the dash or makes the lamp flicker even though the LEDs look fine, this is the part that settles it. Every computer we list is checked against a specific chassis and model year.

    Frequently asked questions

    What does a headlight computer do?
    It is the control unit that drives the headlamp's LEDs — power-up, dimming and fault reporting. When it misreports or underdrives the lamp, you see dashboard warnings or flicker even though the diodes themselves are fine.
    Will it clear headlamp errors on my dashboard?
    That is the most common reason for swapping it. A computer matched to the chassis keeps the lamp's electrical behaviour within what the car expects, which in most cases settles flicker and dashboard lamp errors.
    Do I need to program it after installation?
    The computers we stock are matched to the chassis and plug into the factory connectors — no dealer coding required on the models we carry. Verify the year range on the card before ordering.
    How do I match a computer to my car?
    By chassis and model year — headlamp electronics differ across generations of the same model. Each card states the exact years the unit was verified against; send us your model year if you are unsure.
