I have not found anyone else who has had this problem but I hope someone can help. I have a 1999 Goldwing 1500SE and my left headlight bulb keeps burning out on low beam. Yes the wiring looks ok, replay replaced, housing looks ok,starter switch has been cleaned as well as the high & low beam switch. I have replaced this bulb as a set of 2 3 times in one year! Any ideas as to why only the left low beam burns out?
