hey i have 6k aftermarket kit on my gen 1 ls. they work fine when the car is off, but when ive been driving for a while they start to flicker and now its flickering alot and bugging me. I read that putting a capacitor in there would help, anybody wanna confirm this or tell me what else i should do. Also when i turn them on, they flash really bright for a split second then go to the normal level, is this normal? thanks
