So I have purchased a pair of projector headlights from Spec D Tunning and they came pre-wired so I did not have to much to worry about. I only have to install the original light harness on top of the new one. I wired it up just as the instructions have stated and plugged them in. The driver side works amazingly but the passenger side won’t. Everything else is fine, (Fog, Low, Running, Blinker). I have checked the bulbs and they are fine even have a spare and it is fine. I plugged the headlight into the driver side and the same problem happens. I doesn’t seem to have anything to do with the car wiring just the unit itself.
