1974 Plymouth Scamp (#2)

I had some major problems with lights on my 72 scamp too, when i replaced my rear bumper, the bulbs just decided to quit working when i put them back in: threads were lined up and everything. I ended up just having to take the bulbs out and putting them back in then out and back in over and over again until it got itsself situated... I don't know about yours, but my scamp has a tendancy to randomly decide to make certain things wuit working, and then fix itsself after a certain amount of time...

Well anyway i know my suggestion was pretty lame, but just giving my 2 cents, wish you the best of luck :D
