looking for some advice? I have a 2007 G35x. The passenger headlight comes on when I start the car, but turns off within 15 seconds. If the bulb needs replacing, that fine. But what concerns me, is that the high beams do not function either. In addition to that, I would of assumed the car would give me some warning indicator that the bulb is out.
Anyone have advice on how to trouble shoot whats causing it or had similar issues.
I'd be perfectly ok with purchasing new bulbs if need be.

It sounds like you might have a problem with your ballast on the left side. You can swap sides with the ballasts (left to right and right to left) and see if the problem moves to the right side.

ill give it a shot. Thanks
