Ok well I have a 2001 Chevy Tahoe with 9006 Xenon H.I.Ds (8000k) The problem is that when i turn the car on they flicker when i step on the pedal. The weird thing is that after a bit of driving they stop flickering. could it be because i have to let the lights warm up a bit? I've also done a bit of research and heard that maybe a relay harness will fix this issue? i dont want to buy the relay harness until i know it'll fix the problem. Thanks.
