General
The stop light switch monitors brake fluid pressure in the rear brake line. When the vehicle operator steps on the rear brake pedal and pressure in the brake line reaches a preset level, the stop light switch is tripped and illuminates the stop light. The stop light switch is located on the rear brake line T-fitting.

Installation
Note. Perform step 1 below only if original rear stop light switch is being re-installed, new switches have a sealant contact patch on the threads. If new switch is being installed, begin with step 2.
1. Coat threads of stop light switch with LOCTITE® HIGH PERFORMANCE PIPE SEALANT with TEFLON (LOCTITE® Part No. PST565).
2. Install stop light switch to brake line T-fitting. Tighten switch with a 1-inch open end wrench.

4. Install exhaust collector and mufflers. See 2.7 Exhaust system.
5. Turn ignition switch to the FUEL position and close seat. Then turn ignition switch to the LOCK position.
Caution! When closing the seat, make sure the ignition switch is in the FUEL position. If the ignition switch is in any other position when the seat is closed, the seat latch mechanism could be damaged.
Warning! After completing repairs or bleeding the brake system, always test motorcycle brakes at low speed. If brakes are not operating properly or braking efficiency is poor, testing at high speeds could result in death or serious injury.
6. Bleed brake system. See 1.9 Bleeding brakes.
Warning! Check for proper tail lamp/stop light operation before riding motorcycle. Visibility is a major concern for motorcyclists. Failure to have proper lamp operation could result in death or serious injury.
