All three bulbs in the right rear side of the car are out. All of the fuses are fine, all of the bulbs are fine. Are there any other issues that could cause this problem aside from it being electrical? I looked at the wires going to the sockets for the bulbs and they did not seem damage, and I would think that if it were electrical then it would be all my lights, not just the right rear side.

 

check for voltage on the sockets , no voltage likely electrical ,
brake lights could be a bad brake light switch on the pedal
