I just ran into this same problem today, I have to get it fixed before the weekend. Its serious enought to make me stop lurkin and register. I read through the posts but what was the actual problem?

 

This happend to me, took getting pulled over and a ticket for me to discover it. I fairly quickly found it to be the fuse and replaced it after i replaced the bulb without that working at first. Replacing the fuse fixed it but tonight which is just a few days since i replaced the fuse it blew again. Anybody have any ideas whats making it blow?
