Although xenon headlights are famed for their brightness as well as their longevity, occasionally these headlight bulbs do stop working. Fortunately, replacing a xenon headlight bulb is a rather straightforward and simple task. The xenon bulb resides inside the headlight housing where a regular, halogen bulb sits. The xenon bulb is attached to the wiring harness from the vehicle through the ballast. No special tools are needed and no extraneous parts need to be removed. Expect to spend less than 10 minutes replacing your xenon headlight bulb.

Skill level:


  1. 1

    Turn off your vehicle if it was on and prop open the bonnet. Wait 30 minutes if the xenon bulb had been on, as it may still be hot.

  2. 2

    Disconnect the negative battery cable from inside the engine compartment to ensure safety while working with electrical equipment.

  3. 3

    Disconnect the plug from the ballast feeding into the rear of the headlight assembly.

  4. 4

    Remove the weather cap from the rear of the headlight assembly, covering the xenon bulb.

  5. 5

    Disengage the metal clip holding the xenon bulb in place.

  6. 6

    Pull out the xenon bulb and insert a replacement, securing it with the metal clip, covering it with the weather cap, and reattaching it to the plug coming from the ballast that you removed earlier.
