driving home late one night last weekwith only one head light. the left one burnt out two days before this happened. i drive over a railroad crossing then the right one goes. first response " OH F**K". i drive home going 25mph with my hazard blinkers on. luckily i was only 2 blocks from my apartment. check it out in the morning blew the head fuse. replaced it headlights went down. replaced bulbs. went to go to turn on my highs. burnt the head fuse again. WTF. went back into auto store bought another fuse. havent tried it again. what could be wrong? the lights work just not the highs.
