So lately, one of my headlights will randomly flicker and then turn off. I had a spare [new] ballast so i tossed it in. All was fine for a few weeks and now it's happening again....soemtimes with both headlights, but moreso with the pass. side. Here is where things get a little strange. The ballasts are still getting power just fine, and tapping/moving/tinkering with the wiring and ballasts does NOT yield any results. But, if i turn the headlights off for a moment and turn them back on, then the lights come back on just fine. Now sometimes the light will licker within 5 seconds and turn off, sometimes it'll take 5 minutes to act up or it won't do it again at all.

Anyone have any ideas?

 

I had the same thing happen to my driver side HID's a few weeks ago. Did you notice that the bulb took a little longer to reach kelvin when you tuend the lights on before the flickering happened? I replaced both bulbs because it had been 3-1/2 years since I bought the kit and haven't had the problem again. I have McCullough ballasts. What kind do you have?

 

You mentioned they were getting power, but did you check your grounds. My driver's side one cut off on me one night, so I shut them off for a few seconds, turned them back on and it worked, however, it flickered while it was warming up. The ground wire had wiggled loose from the connector they put it in when they made the kit.

 

i guess i'll check the grounds tomorrow..... after i replace the coolant lines to the turbo.
