Hey Everyone,

I just got a "check tail light" and "check brake light" warning today, 04 e53, and when I went back to take a look, my driver side bottom bulb was burned out with running lights on. I propped the brake pedal, and the light came on dim like the other running light brightness. The passenger side bottom bulb came on bright like a brake light is supposed to be.

Are the bottom bulbs supposed to be the brakes, or are all 4 reds supposed to go bright for brakes? I don't have another e53 to compare to, and I couldn't find any photos or video online.

Also, my passenger bottom bulb socket is a green one with 3 contacts and a dual filament bulb, while my driver side bottom socket is white, 2 contacts and a single filament bulb, same as the middle two sockets. No way that would work for both running and brakes with a single filament bulb right?
