I have low beam hids in my vette. Lt one quit working and so i started tracking the problem. The bulb was fine checked it on my buddies truck. I put a new ballast and old bulb on the car and it worked for a few min then couldnt get it to come back on. In the mist of trying different bulbs and what not my high beam on the lt side stop working as well.. Wtf!!! Now my lt side low or high does not work at all.. Is there a fuze that controls just the lt side i begining to wonder if i have a electrical problem bad ground or something.... I know this is a long shot and could be a few reasons for this im going to take a test light to it after i get if off the lift and start there.. Could someone give me some info on the fuze setup on the c5's???
