Thanks for the info, guys! I initially had the driver's side ballast die, due to moisture getting into the electronics. I got a used ballast replacement and had it installed, and problem was fixed .. for 4 days. Then it went out again. had my mechanic thoroughly swap out and test everything from ballast, igniter, and bulbs, as well as continuity in the wiring. He couldn't find anything wrong, except that the ballast must be out. After this testing, the passenger headlight started going on and off and random. I feel like it's all related and that there might be a short in the wiring somewhere. Any ideas? Thanks in advance for your help.
