The Roadmaster Brake Light Switch is used to connect InvisiBrake, BrakeMaster, or an Even Brake motorhome monitor 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. Although designed for Roadmaster braking systems, these brake light switches can be used to monitor the braking activity of any system that moves the brake pedal.
Other manufacturers’ motorhome monitors are connected to the supplemental braking system. They can only tell you when the supplemental braking system is on or off. They cannot tell you if the towed car’s brakes are on or off. If the braking system malfunctions or is installed incorrectly, you could be fooled into thinking your brakes are off when they are not. This is 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.
NOTE: Roadmaster brake light switches are vehicle specific. Each kit includes a mounting bracket and installation instructions for a specific application.
• Work with any supplemental braking system that moves the brake pedal
