thought i would see what insight you all have on my issue: not sure whats up but sometimes my dash lights will be way dim and one headlight will be way dimmer than the other one when i turn my lights on. its not a fuse they are all good...was told it could be my voltage regulator which is inside the alternator so i just replace the alt. bc it was old anyways but i still have the same issue! any thoughts??

Year and model would help but I'm guessing the relay for the left hand light.....it supplies power to the left light and the running lights........when out the headlight on that side will glow dim from backfeed through ground side of other bulb still on.

sorry its a 1991 Loyale...sweet thanks i will have to check that out in the morning!

Bellingham huh? Let me know if you need some help!
