So I have a 2002 that when you turn on the headlights...the driver side will flicker hard and shut off after about 3 seconds. i have replaced the bulb as well as the ballast and still have the same issue. Fuses make no sense as i have some power to the headlight and i'm lost. checked all the grounds i could find and wondering where to go? thank you for any input.

 

mine just started doing this, as well! I just swapped bulbs and no luck...

 

Happened to me before(DC2-R)

Just whip out a multimetre and see what voltage you're getting out of the headlight harness. Anything below 12v or whatever it should be would have to be the problem.
