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 vehicle’s OEM brake light switch doesn’t work when the vehicle is in ‘tow’ mode. Both the universal switch and our vehicle-specific switches are only activated when the brake pedal is depressed — with this system, you'll always know if the towed vehicle's brakes are on or off. 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. 610046 751000 Universal brake light switch... Vehicle-specific brake light switches Roadmaster also makes vehicle-specific kits. Check your vehicle at your local dealer. 61-0046 751000 shown Why do I need one? A Brake Light Relay stops the brake lights from functioning until the vehicle is started. This prevents the towed vehicle’s brake signal from overriding the motorhome’s turn signal. When you tow without a Brake-Lite Relay, your towed vehicle’s brake lights alone will work fine. Your turn signals alone will work fine. But if you’re braking and turning, the brake light from the towed vehicle will override the turn signal from the motorhome and drivers behind you will be unaware you’re about to turn. You only need a Brake-Lite Relay if you’re installing a supplemental towed vehicle braking system that pushes or pulls the brake pedal. Exceptions – • With the engine off, step on your brakes. If the brake lights do not illuminate, you do not need a Brake-Lite Relay. • If you’re using magnetic tow lights or a bulb and socket wiring kit, you do not need a Brake-Lite Relay. • If the motorhome and towed vehicle are wired for separate brake and turn signals, you do not need a Brake-Lite Relay. 14-6093 88400 Brake-Lite Relay 88400 shown • Truly universal — works with all braking systems that depress the brake pedal. • Line-of-sight transmission confirmed to 1,000 ft for long range reliability • Confirms each audio signal at 100% reception • Protects the towed vehicle’s brakes — reports any braking activity to the motorhome monitor; includes a low-battery alert, extended braking and break-away alarms, and five other audio and/or visual alarms and system status notifications. • Easy install, all at the towed vehicle.
