Well all the lights on the right assembly work however when I brake only one of them shuts off. So what I also tried was switching the light bulb from the left (which works when I both brake and don't brake) to the right and vice versa and the same thing. So I don't think it's the light bulbs.

I think it could be the actual light bulb socket. What do you think?
Yes the bulbs are dual filament.
