Replacing Your Car's Headlight Igniters
Xenon light bulbs usually need a large amount of voltage, about 15,000-25,000 volts, to start. This is where the headlight igniter comes in. They amplify the voltage being fed into the light bulb to give them the necessary boost needed to illuminate the bulbs. If these devices begin to fail, you'll obviously have great difficulty getting your headlights to start up. Replacing a broken headlight igniter is a rather lengthy and complex process that requires experience and patience on your part.
Difficulty level: Moderate
Tools that you'll need:
- Headlight igniter
