Hello Everyone! Can someone please help or tell me if they've had the same experience. I recently upgraded my fog lights to HID bulbs. Basically the way these HID bulbs work is I have to turn them on with the high beam switch and not the Fog light switch. Yesterday when I installed them they worked perfectly. Today when I tried it the passenger side Fog light wasn't working. I've checked the wiring, the ballast, the bulb...nothing was wrong. I then took the stock halogen bulb to test somethings out. When I turn it on with the fog light switch it works, but when I try to turn it on with the high beam switch it doesn't work? I dunno what happened? Please let me know if anyone has any suggestions. Thank you.
