Hi there,
So my right brake lights are out- completely. I went out and bought the lights and got ready to install them, but had a lot of trouble figuring out which light to replace. I turned on my headlights, and it appeared that what I thought were brake lights were also tail lights, and were working fine... at least as tail lights. When I hit the brakes, they don't come on, only on the right side. They are two filament bulbs- does it use one filament for each purpose? Or is there a connection issue? Or have I just not found which light is the brake light? Where should I look next? Any help would be appreciated.

It's a dual filament globe, and only one filament has broken. Hence why the tail light is working, but your brake light is not.

Replace the bulb and it'll be fine.

 

check your fuse box under the hood and look at the horn/stop fuse
