Easily install a pressure-activated brake light switch anywhere in your brake system! This special banjo bolt has a built-in 2-wire switch to actuate your brake light relay (not included). The shank of this bolt measures 30mm (1.17") long to go through two banjo fittings. Copper Crush Washers (Part No. 3241-3/8) sold separately.
Note: The amperage rating of this compact switch is quite low. It should never be used to switch on brake lights directly. Only use it to trigger a brake light relay (sold separately).
