Our Hydraulic Brake Light Switch provides a pressure-activated switch closure to actuate brake lights. The 1/8 NPT male threads make plumbing easy. Just add our 3AN Brake Light Switch Tee (Part No. 3209-02-03S, sold separately) to connect the brake light switch to a 3AN brake line.
Two #10 screw terminals allow easy wiring. The maximum current rating is 5 amps. If your brake lights draw more than 5 amps, you must use this switch to activate a brake light relay. Switch closes at 60-120 psi.
Inoperable brake lights will get you bounced at Tech Inspection, so carrying a spare switch is cheap insurance!
