    My xenon headlight intermittently turns off, then back on.

    Guest-only advertisement. Register or Log In now!
    I have a 2005 A4 1.8T USP. When I get into the car at night, both xenon lights are on, I start driving... couple minutes later, I see the passenger side headlight turn off, the bulb out warning comes on "dipped right headlight" then shows a O with an X in it (bulb out), then the xenon light will come back on eventually. Sometimes it will flicker a few times, sometimes it will be once. regardless, this is a huge problem that I have! What should I do?

    I had my friend drive my car and I drove in front of it in another car at night to see what it looks like, it looks like its winking at me lol

    Help?

    Thanks, Matt.

    Re: My xenon headlight intermittently turns off, then back on.

    Check your ballasts. When ballasts reach their end of life, they start cycling -- that could explain the flickering that you are seeing.

    Check the bulbs first (swap left and right) to identify if it's a bad bulb or a bad ballast. Mostly it's the bulb only.

    Ok I had same problem, and jumped to conclusions and bought bulbs. It ended up being one of the wire/connectors going to the ballast. SO take it apart and jiggle wires, etc around.

    Aftermarket or OEM?

    OEM, NO change in color. I will try swapping each side and see what that does... If anything, I guess I will need to buy a bulb.. or ballast.. Wish me luck!. LowestA4, If I need a bulb, I will let u know. Thanks for the PM

    ^ I have the same problem. Was the bulb or the ballast in your A4?

    I switched the bulb sides and the bulb is broken not the ballast.
