i've never had a problem with my hid's until the other day. i have the auto headlights deactivated. it's only the driver's side headlight. i noticed the other night one was out and i turned them off and back on and they were both lit again. i tonight noticed when i was behind someone it was out again. i tried the off on method again and noticed in the reflection it would start to glow and then die. i tried this 3 times on 3 different off on methods before it lit back up on the 4th try. now later tonight it was off again and i couldn't get it to glow or light at all. sound like a bulb or a ballast?
