Product Description
The Roadmaster 155 is a self-contained (bulb-and-socket) towed-vehicle wiring kit. Instead of tying into the towed vehicle's lighting circuits, it adds its own independent sockets and bulbs inside the taillight housings, with wiring routed from the taillights forward to the grille area where it connects to the motorhome's signals.
Because the towed vehicle's electrical system is bypassed entirely, there is no interaction with the vehicle's electronics and no concern about voiding the vehicle manufacturer's warranty. It's a good choice for owners who prefer not to splice into the vehicle's factory wiring.
Taillight housings vary by vehicle and need room for the added socket. Contact us with your vehicle's year, make and model if you're unsure about fit.

Pro tipWiring and battery tips
- Protect the car’s wiring. Diodes or a separate bulb kit keep the motorhome’s lighting signal from feeding back into the towed vehicle’s electrical system.
- Watch the battery. Some vehicles drain their battery when flat towed; the owner’s manual will say whether you need a charge line or battery disconnect.
