TA Dreaming

ok it seems that my brake lights arent working all the time. the third light works always but the other two actual tail lights dont. so i backed up to a reflective surface(ie the apt dumpster). it does not matter if the parking lights are on or not. what does matter though is whether or not i have the steering wheel tilted. i ride with it pulled down to the second to last position. in this position the brake lights dont always work. however if its in the position just above that they always work. i can actually hold my foot on the brake and go between these two positions and watch the brake lights come on and go off. the third light always is on during this too. sometimes i can get the brake lights to come on and stay on when i move the tilt. not sure what im doing to do it, but ocne they are on im assuming they work from then on out. so WTF can be casuing this. thanks trey
