Dim tail light

I've got a 1964 f100, and the left tail light is much dimmer than the right one. I changed the bulb and it didn't help. Any advice on where to start?

Check voltage. Check ground continuity. Check all connectors. Clean everything.

That should do it.

Have the wires been cut? If so they may be hooked up incorrect.When you put the brakes on is the brake light on the "right" dimmer than the left? Which filament is lighting when the lights are on, the short or tall one? Should be the short for running lights and tall for brakes.

Success!
The bolts and washers that attach the bracket that holds the taillight to the bed were rusty and corroded. Cleaned the bolts and washers
and put on new nuts so the ground is solid and lights work perfectly.
