My headlights here lately have been going on and off as I am on my way to work. The grounds are all good, it seems like the light switch could be the culprit? The reason I am saying this is while rotating the knob back and forth in and out seems to find the correct spot and keep the lights on.. I basically thought just pull the switch all the way out and have lights no matter where the knob is rotated at. What do you think there Bolters?
