Hi, I searched and found others with the same problem; but no one really resolved it.

I lowsided a few weeks ago and broke a few parts. Mechanically I basically had to replace the gauge cluster and right foot peg. I put everything on today, but the brake light doesn't work. The previous owner installed an integrated tail light kit and it worked fine before. The two bulbs are on, and both filaments in each bulb are fine. I'm not sure if its the running lights and the brake lights won't come on, or if its the brake lights and they won't turn off; they usually pulsate if they're being applied though. I checked the front lever and switch, they're ok. Does anyone have any suggestions or experienced this before?

Thanks

 

The switch is a fairly straight forward set up, little metal tang on brake activates it, it goes into a plastic body with an adjuster on it (plastic ring on plastic thread) Located below the brake pedal. Since you replaced the foot peg, the 'off' may have bent the brake just enough to either have it on all the time or not enough to activate it.

 

I replaced the entire pedal assembly. Even with the switch entirely out of the bracket theres no difference. I tried adjusting it every possible way and pulling the pin/spring down completely, then letting it in completely. Fuses are all fine, and I didnt touch the wiring.

 

Looks like a good time to take out a 12v test light and poke to see if you have both brake and running on. At least with that you will be able to see what your working with. Then you can start tracing things out to see what's acting up. Could turn out to be bad connections, ground (doubt cause you still have lights on), broke wire, could even trace back to the fairing stay area...that's the fun of electrical
