I'm not so sure it's a grounding problem, but that's certainly a possibility.

Grounding for the front signal lights is a big problem in the pre 69 cars, but 
the rears seldom have a problem because the backside of the rear lights is 
protected rather than exposed like the fronts are. If it IS a grounding problem 
I think you'd do well to just remove one of the mounting screws and grease it 
under the head where it engages the metal of the light base and on the threads 
where it engages the fender anchor. The grease will exclude moisture and retard 
corrosion. That may be all you need to do.
