Tail light problems

I got a 50 Ford and the tail lights were working fine. Then they just stopped. When I flip the light switch they don't go on. When I hit the brakes they barely glow and when I hit the blinkers they are a little dim. Head lights work fine though. Any advice?

 

Check your grounds.

 

sounds typical of a bad ground to me too

 

Tail light fuse blown?

 

+1 on a bad ground. Run a temporary one if need be and check again. If they come back to life with a temp ground, you have found your problem.
