Product Description

The Roadmaster 751475 is a brake light switch kit (stoplight switch) used to connect a motorhome brake monitor to the towed vehicle's brake pedal. The switch mounts at the brake pedal so the monitor in the motorhome is alerted whenever the towed vehicle's brake pedal is applied by the supplemental braking system.

A kit like this is needed when the towed vehicle's factory brake light switch doesn't work for monitoring while the vehicle is in tow mode. Roadmaster stoplight switch kits work with InvisiBrake, BrakeMaster and Even Brake monitors, and Roadmaster makes them for specific vehicle applications.

Compatibility

  • Roadmaster InvisiBrake, BrakeMaster and Even Brake motorhome monitors

Roadmaster brake light switch kits are vehicle-specific. Contact us with your towed vehicle's year, make and model to confirm this is the right kit before ordering.

Pro tipSupplemental braking: what to know

  • Often required by law. Most U.S. states and Canadian provinces require brakes on a towed vehicle above a certain weight, and towing equipment makers generally expect one.
  • Match your motorhome. Some systems are designed for coaches with air brakes and others for hydraulic brakes — check which your RV has.
  • Portable vs. permanently installed. Portable units move between cars; installed systems are quicker to hook up day to day.
