yeah i was pretty sure it was a fuse, but i won't mess with it till i get the lights out. The white backing on the door light wasn't moving, even with the tab pushed, and it'* probably gonna have to get broken it looks like now...

Well, if that'* the case I'll bring one of my extra'* on Saturday (I have two full sets of extra white backings). No charge.

the problem I've ran into with teh lights in the doors on the Bonneville is that once taken out people usually brake them so that every time you slam the door the light will fall out of the door. The previous owner probably used some really strong glue to glue the light back in so it'd stop falling out. :(
One nice thing is that your lights are removable from the front, I have to remove the entire door panel and change the lights from the back side, it'* a PITA.

Yeah I hate it, everyone slams my doors, infact one of my family members knocked the cover off of the rear one yesterday.. :?

I'jm gonna try to do it. It should work...
