Jeff J: This is a direct replacement for your banjo bolt and secures to your brake line. It's a pressure activated switch. It's a very easy install, but you will have to bleed the line(s) again. Make sure you order the correct thread pitch for your application. Jun 25, 2014

Chris M: It replaces the banjo bolt. Very simple - Doesn't come with instructions. It has a pressure sensor switch in the bolt that makes contact when the brake system is pressurized (braking). The thread pitch has to match your factory banjo bolt for it to fit. Jun 24, 2014

Jeffrey B: The old banjo bolt on the rear brake master cylinder needs to be removed. Then place the new brake light switch banjo bolt into the master cyclinder. Splice the two wire leads into the rear tail light plug and your good to go. Jun 25, 2014

Curtis L: The 1.25mm switch works for the big 3 Japanese manufactures. It worked perfect on my 2012 Yamaha YZF-R1 (annerversy edition). But be careful when splicing the wire, cause you don't want to cut it too short. Jan 13, 2014
