For some unknown reason, the right main tail light and the smaller side one do not work when lights are turned on. Brake light works, so its not a bulb issue... Fuses all check out ... I am baffled. Anyone heard of this issue? Thanks

 

It's probably the seat where the two contact points from the bulb make contact with the metal parts on the connector. Sometimes they get corroded or simply fall apart. If not the fuse, this would be my next guess. I had to replace the rear bulb harness on one side of my car.

 

Thanks, I'll get deeper into it but it just is odd that both the bulbs are unrelated other than they both are in the same circuit... and I do not believe the left and right side are on different circuits....
