On my '06 2500, when I hit the brake pedal, the brake lights do not come on. When I hit the turn signal indicator, the turn signals work fine. The 3rd brake light does work when I hit the brakes.
This doesnt sound like an issue with bad bulbs, does it? I sure hope its not some sort of difficult wiring issue....Im going to look into it in a little while, I just thought I'd see if anyone has dealt with that type of issue here first.

Thanks!!
