stoplight switch kitWhy do we make stoplight switch kits?

ROADMASTER uses the stoplight 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 stoplight 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.

How can you tell if you need one?
If the brake lights do not work with the towed vehicle's ignition key turned to the "tow" position, you need a stop light switch kit to make your vehicle legal to tow.  

Find out if your vehicle needs one.
