My right stoplight on my '87 Firebird does not work. Since there are two on each side of the car, and they are both at the furthest ends from center, the picture in your mind should be the two on the left working and on the right, the furthest one from center not working. The tail lights all work. I tried taking the neighboring bulb and putting it in to make sure there was no size problem with the same result. When tested, if the break pedal is hit, the bulb dims when you take the taillight off of the car and watch how all of the bulbs perform. The bulb only has a faint glow like a hot wick from a candle just extinguished but not yet fully out. Again, the neighboring stoplight that is closer to center is fine. I am in no position to have someone fix this so I have to tackle it myself. This is the first problem I am going to focus on.

 

I had a problem similar to this, my entire right side brake lights wouldn't work. Problem ended up being the dielectric grease some previous owner had used. It had dried out and didn't conduct electricity anymore. I scraped it out and it worked fine after that.
