Brake Light Switches
Why do you need a brake light switch? Brake light switches are necessary only if you're installing a supplemental braking system monitor, and the vehicles OEM brake
light switch doesn't work when the vehicle is in tow mode.
Both the new universal switch and our vehicle-specific switches are only activated when the brake pedal is depressed. No other manufacturer provides brake light switches
with this level of specificity - if you know when the towed vehicle's brake pedal is depressed and released, you know if the supplemental braking system is positioned properly
and working as it should.
Why do we make brake light switch kits for vehicles?
ROADMASTER uses the brake light switch to connect InvisiBrake, BrakeMaster, Even Brake and 9700 motorhome monitors directly to the towed vehicle's brake light, so you always know when the brake pedal is depressed and released.
It's simple — brake light on: monitor on; brake light off: monitor off.
If any particular vehicle's brake light switch doesn't work when it's being towed, we make one for it that does.
Other manufacturers' motorhome monitors are connected to the supplemental braking system. They only tell you when the supplemental braking system is on or off.
That's an important distinction, and here's why: Say the braking system is positioned too far forward, so it's riding on the brake pedal. Every ROADMASTER monitor will
accurately indicate continuous braking, notifying you of a problem before you even drive away. But motorhome monitors that are connected to the supplemental braking system
will have nothing to report. That would likely result in brake damage.
Vehicle-specific brake light switches
If the brake lights do not work with the towed vehicle's ignition key turned to the "tow" position, you need a brake light switch kit to provide a signal to the supplemental
braking system. Roadmaster manufactures both vehicle-specific and universal brake light switch kits. Check FitMaster

751XXX Vehicle-specific brake light switches
Universal Brake Light Switch
This switch sends a beam of infrared light to detect brake pedal movement. When the pedal moves down, it sends a signal to the monitor that the brakes have been applied.
• Works with any supplemental braking system that moves the brake pedal
• Just three wires — one wire to the brake transmitter, one to ground, and one to power
• Can provide a brake signal to any motorhome monitor
• Mounts to the brake pedal arm under the dash
• No bracket
