Brake light on when lights are on

Hi,

I know this is an old thread but it sounds exactly like what happened to me today. At first the bulb indicator came on every time I pressed the brake. So I thought it was the brake bulb. So I turned on the lights and indicator came on and stayed on. Now I have noticed that when the lights are on, the third brake light is on and when the lights are off and the car running, when I press the brake, all the interior lights come as well. Could this all be coming from a bad brake bulb? It's hard to believe that it could all becoming from a bulb but after reading your thread, I'm starting to think it is the same thing.

Any help would greatly be appreciated!

Lights out

Not sure what could causing the lights to go out on your dash and interior...however, I didn't think a melted bulb on the tail light would cause my interior lights to come on when I pressed the brake pedal. I would look and the outside lights first to see if any are not working properly. The lighting system in these w140's are amaxzingly wired.
