Exclamation Xenon headlights flickering:(

I have xenon headlights and they are flickering. When they flicker it is both of them, not just one side so that leads me to look somewhere other than a ballast. It is like they turn off and back on in a blink of the eye. If anybody has any insight it would be greatly appreciated.

Thanks

I think that is just for when you are adding HID lights to a car that didnt have them OEM. Mine and the original posters problem is with original xenons installed and looks to be a ground problem.

I have since replaced both fron bulbs and my lights still flicker. I looked at my tail lamp housing and they are different than the ones that there is a fix mentioned for above. I have a 2000 and that fix is for 2001+. I examined the connectors and they showed no signs of corrosion or burnt connectors. I was hoping maybe someone eles with a pre-01 car might have had this problem and fixed it. Any insight is much appreciated.

That would be me!

I had the same problem, and also have the same housing as you. For me it was as simple as taking each bulb out of the socket in the taillights and putting them back in. Problem solved-no more flicker.
Two months later the problem came back. This time I went to autozone and bought new bulbs. ($12 for all six bulbs)
Havent had a problem since..........

Flickering lights is a sign your transformer is on the fritz.
I'd suggest getting it looked at, shouldn't cost much to replace.

No its not.
Flickering lights is a sign of a bad ground, usually in the tail lights. It causes the light control module to keep resetting itself, and this causes the headlights to flicker.
