Passenger side parker light not working

[listen_to_slayer]

Lately I've noticed that my passenger light has been yellow compared to my drivers side, found that it was my passenger side parker bulb (not the H1's or H4's) and I just changed the bulbs all round and still no luck.

I've recently had a aftermarket headunit installed, could this have caused it? (somewhere in the wiring) or would it be a fault somewhere else? Anyone else had this?

Thanks,
Adam

just buy some white T10 LEDs, they look better and will last longer

i dont think its the light itself, there is a fresh parker in it and that wont work, so im guessing LEDs wont work either :S
