I appreciate this site and have learned alot from poking around and reading. I have an issue that I need help with. My driver side headlight went out. Definitely a bad bulb. I replaced that. Tested, everything lit up as it should. Later that evening , went for a drive to my sister's. Headlight worked. When we came home, did not work. Next day, worked, then didn't work. In the last, I've had motorcycles with HID lights. This happens, it points to a ballast. Replaced the ballast. Drove the car today, same issue. Worked, drove around, turned off the lights, then back on, no go. I've read it is probably the igniter. I've seen several posts on the web where ppl replace all 3, bulb ballast and igniter, to be safe. Any input? Any suggestions? Thanks in advance, I appreciate any help
