I have '02 TL-S and over the past 6 months I've been experiencing a problem with the drivers side headlight.
About 1-2 times every few weeks the headlight on the drivers side will not turn on or will turn off while driving. Most of the time I just turn the headlight switch off, wait 10 seconds and turn it back on and the headlight will work again.
From what I have read this is a problem with the ballast showing some wear or electrical board is corroding. I was looking to buy a brand new one and take the bumper off to replace it but a new one is about $300 bucks. That's a lot of money.
Should I just throw $300 bucks and buy one or does anyone have some suggestions?

 

swap them around first and see if the problem stays in the same spot or moves.

if problem moves = replace ballast

if problem remains = find the fault in the wiring

 

X2 swap bulbs around first. The problem you describe was like mine and it was the lamps.

Had this problem too, just bought new bulbs installed them and all is well.

 

I think I am going to start by replacing the bulbs first. Where do most forums member buy their bulbs?
It looks like I can get to the passengers side bulb easy but the drivers side looks a little more difficult.

If it still happens after the bulb is replaced, then I most likely I have a ballast or electrical problem.

 

did you try swapping the bad side with the good side one first? may not be a lamp problem...but... HIDextra sells them in our vendor section. check with him. stock color is 4300k - best output.

driver side - you have to remove the overflow coolant reservoir for room. a lil cramped but it can be done.
