Last summer (2012) I put 8000k HIDs in for my low beams. They worked fine until around September. The driver side light always works but the passenger side will randomly not turn on. When this happens, the ballast makes a short loud buzz and the light fails to ignite. Sometimes (rarely) the light will come on after turning the headlights on and off a couple times. Other times both lights will work perfectly. Sometimes, the light will both work and fail in the same day. I've never had the light turn off while it worked (during driving). Any one have this problem, a solution, or any ideas for this problem? Thanks
