fitted my inpro's with 6000k HID's, all worked ok. then driving home at night went over a pothole and the drivers-side main beam went out, sidelight was still working. i thought it was a connection on the HID's so took it out and re connected but still nothing. thought it might be the ballast, so swapped it for a spare. still nothing. disconnected the HID's on both sides and put some standard bulbs in, and now neither side main beam works, but both the sidelights do :^) very puzzled anyone got any ideas what it could be?
