I had factory HID lights and they have been acting weird lately, so I thought I would see if anybody else had a similar problem. I will be driving down the road and one of the headlights will randomly go out. I will turn the lights off and back on and they will work fine. Sometimes I hit a bump and they go out so I checked to make sure everything is plugged in and they are. I even went so far as to put a piece of electrical tape over the plug to make sure it's not loose. It's becoming more frequent and really starting to piss me off!
