Tail light issues

Ok so here's the issues I'm have. One tail the brake light works, but when I turn the lights on it won't light up. The other light is the opposite. It will light up when the lights are on but the brake light doesn't work. I replaced the bulb on one of the tail lights and still the same issue.

Make sure your taillights are well grounded. Weird things like this often occur when there is a lack of proper ground.

I soldered a wire from each bulb holder and ran it to a clean ground.

As others mentioned, check the grounds.

Check the wires from the back to the front.

However, I had a bad headlight switch once, where the lights worked except the headlights.

So, keep that in mind. When they go bad, they act weird.
