I got a '01 325i and I got a whole new head lights with HID installed about a year ago. Some time a few weeks ago when I turned on the headlights the right headlight was putting out a shade of green light instead of the bright white light that it did before. Then a few days later the right headlight stop working at all. Then a week after that the left headlight stop working as well. I checked all the connections and are all the same as before. Now when I do try to turn on my headlights only the left one blinks for a second but never turns on. I never performed any type of maintenance on the headlights. Is their any think I can try to attempt to see if I can fix them or do I have to replace the HID units.
