Not sure on where to start to diagnose this. No rear brake light when I depress the brake pedal. The rear break lights DO WORK when I pull the handle bar brake lever?
Parking lights (when ignition is on) and turn signals all work fine.
I'm going to say more than likely it's going to be the brake light switch. They get hot, especially when you have exhaust running down along the bottom of the bike where it's at. You can bypass it with a paper clip and check it. You tube has videos on how to check it like that.
