I have a '93 Subaru Impreza. When my headlights are on, the rear "running lights" are on, too. When I step on the brakes, my left brake light comes, but the right side goes dark! (dual-filament bulb, goes completely dark).

I replaced all the bulbs, as well as scientifically removed them one-by-one, but the result remains the same: depressing the brake pedal causes the right side to go dark.

The ONLY electrical monkeying around that could have been done was 2 weeks ago when I had my tranny rebuilt. When I picked the car up from the shop, I noticed my car's radio was "reset" (flashing 12:00, and lost all my station presets).

Any thoughts on this?

Thank you
