This Aprilia RS660  Brake Pressure Switch allows your rearset to operate the rear brake light. This all-in-one unit replaces the banjo bolt that connects the rear master cylinder to the rear brake line. You simply replace the bolt with this assembly and splice the wires into your existing brake light switch. The pressure inside your brake system then activates the brake light.

Installation requires the disconnection of the battery terminals as well as unplugging and removing the OEM brake pressure switch.

NOTE: Color of plastic collar and connector may vary.
