Default Xenon Headlight Flicker Problem

Both of my xenon lights work fine when first turned on. If I turn them off and turn them back on they will flicker and strobe.

Quickly turning them on and off several times will get them to act normally.

Just curious if anyone else has experienced similar symptoms.

Default Igniter issue possibly

Mine flickers when there's some vibration (ie.: driving vs stopping), though it has started to flicker on it's own while stopped. Sometimes the thing just cuts out completely but turning it off, wait a few seconds then turning it back on revives it.

I have the car going back in next Thursday to get a control module replaced. Not sure what the part number is but I'll post it here. Dealer only took it in after showing them that the right headlight was out.

Default Does the flicker occur with both lights?

I would agree on an ignitor or ballast issue if it was isolated to one light. I seem to have a problem that affects both lights.

I would appreciate an update once the dealer fixes your problem. I am wondering if its the 'vehicle electrical control module' which is the only thing I can find that is common to both lights.

Default I noticed it flicker once on the left side but is very infrequent

Or I could have mistaken it for the right but I doubt it.

Once I get the part number(s) I'll post it up here as I know a lot of people are experiencing similar issues and the dealer won't fix it because they don't see the flickering at the time and the issue is tough to duplicate.

Default Exact same issue, turning on and off stops dash error msg.

The dealer "tried" twice to fix the issue, didn't have it happen at the time. So, it still does it. Just a real annoyance.

Forgot to mention: It's on the left side also.
