Last week when I was driving home I blew out both of my headlights. I have been trying to figure out why, but at this point I can not find any wiring that is grounding out. Whenever I turn on my headlights wether they are plugged in or not my voltage meter starts jumping up and down and all of my lights start flickering. The only other symptom is that when the car is off and i turn on the head lights I can hear what sounds like the light switch in the dash is clicking. I am not sure if this is because the switch is bad or if it is because something is gorunding out. I will take any help i can get.
