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 22mm (0.93") long to fit standard banjo fittings measuring approximately 1/2" thick.* 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).

* This bolt will not work with thin banjo fittings (including those used on our Premade 3AN Hoses) without modification.

Harley rear brake light fix


I needed to replace the rear brake light switch on my 2015 Harley. It has a combined banjo bolt/pressure switch but due to vibration the original lasted less than 1,100 miles. This item from Pegasus solved the problem in a very economical way and in a fashion that might eliminate future problems since it has electrical leads attached that can be secured.
