I am having a problem with my passenger side HID light. I drove over a bump (not even fast) the other day and my passenger light went out. I tested the bulb and ballast and found no problems with them. I think this is a problem with power not getting to the ballast, but really weird how it just happened going over a bump. To make matters worse my girlfriend had the same problem with hers, but it's the drivers side. Would replacing the stock 10amp fuses for a 20amp fuse make any difference?? And yes I had a complete HID kit from XenonHIDworlds.com (BI-Xenon H4's). It came with 2 30 amp fuse's and ground wires and control box. Do I need a Relay? If anyone has had this happen, please let me know. It really bugs me having 3 lights HID and 1 light halogen, what a difference. Thanks guys.
