Hi, not sure about this problem. I did the oem fog light installation a while ago on my 4 cylinder. Although since I installed these one light has always appeared brighter than the other?
I bought the two lights out of an oem 2010 (as far as I know). I thought that either the aim was off or one bulb was just tired.
Today I got around to taking a better look at the alignment and all looked good. So I went and bought two new 9145"s and installed them. Guess what, same deal.
The mirror finish on the interior looks the same... I think i know the next step (get a multimeter and check voltage at the bulbs) this isn't making sense Could it be the aftermarket (eBay) relay?
