This was a poor design idea. The factory brake switch could have been utilized if only there was a pawl designed into the rear brake lever as on the factory brake lever. Instead you have to tap into the hydraulic brake system to allow the rear brake light to function. Worse yet you have to cut and splice the factory brake switch which I was not happy about. The product functions and works as intended but I really wish that It used the factory brake switch to activate the brake light from the rear brake pedal. If the bike wasn't going to see any street time then I would not have installed it at all as it is not needed at the racetrack.
