Product Description
The Roadmaster 154 is a universal, diode-based towed-vehicle wiring kit. It connects the towed vehicle's own turn signals, running lights and brake lights to the motorhome's lighting signals so the towed vehicle lights up along with the motorhome while flat towing. The diodes prevent electrical feedback between the two vehicles and protect both electrical systems.
The kit uses four high-power diodes, typically installed near the taillights, with a 30-foot strand of 4-wire cord to carry the signals from the front of the towed vehicle to the rear.
Some newer vehicles with multiplex or LED lighting need Smart Diodes instead of standard diodes. Contact us with your vehicle's year, make and model if you're unsure which kit you need.

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.
