When towing, guessing whether the towed vehicle’s brakes are actually engaging can lead to stress and potential damage. The Roadmaster Universal Stop Light Switch Kit activates your RV’s brake-monitoring system only when the brake pedal itself is pressed. That means your indicator light reflects true pedal movement, not just a system signal. You’ll always know that the brakes are being applied exactly when they should be—and that they’re releasing fully when they shouldn’t.
Improperly positioned braking systems can keep pressure on the pedal even when you’re not stopping, wearing down tires and brakes. By directly sensing pedal position, this kit ensures the system isn’t continuously applying force. It helps you avoid costly wear or damage that other signal-based systems can’t detect. When the pedal is up, you know the brakes are off—simple peace of mind every mile.
The switch runs on 12 volts and installs with just three wires—power, ground, and brake-light connection. It mounts under the dash on the brake-pedal arm, keeping things tidy and out of the way. You don’t have to splice into complex circuits or track down hard-to-find factory wires, making it an easy fix for vehicles without an accessible stoplight circuit.
If the unit ever loses power—like when you swap a battery—the sensor can be reset in seconds. Just press and hold the recessed “home” button until the LED finishes flickering, and it’s ready to go again. No recalibration, no complicated steps—just a quick reset and back on the road with full brake monitoring.
Flat towing can be a much more convenient way to take your car RVing with you than using a trailer or a tow dolly. It'll save you storage space both at home and at the campsite, and it takes less time and hassle to hook up.
To flat tow your vehicle, there are 5 basic components you're going to need: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a flat tow braking system.
| For the RV | Between the RV and Towed Car | For the Towed Car |
|---|---|---|
| Hitch | Tow bar | Base plate |
| Wiring plug | Safety cables | Braking system |
| Wiring adapter cord | Wiring kit/diodes |
The custom-fit base plate installs on the frame of your toad so you can connect the car to your RV with a tow bar. Hook up safety cables between the vehicles to ensure that the toad does not separate from the motorhome if the tow bar becomes detached. Tow bar wiring syncs your vehicle's signal lights with your motorhome's tail lights, as required by law in most states. Finally, the flat tow braking system - also required in most states - activates the brakes in the toad when you hit the brakes in the RV, making for smoother, safer braking, and preventing wear on your motorhome.
