Product Description
The Demco 9523010 is a universal towed vehicle taillight diode kit for flat towing. It wires the towed vehicle's own taillights to the motorhome, so the running lights, turn signals and brake lights on the car work along with the motorhome's lights. The kit uses four heat-sealed diodes that let the signal pass from the motorhome to the towed vehicle while blocking electrical feedback that could otherwise damage either vehicle's wiring.
Once it's installed, the wiring stays on the towed vehicle, so there are no magnetic tow lights to set up and take down for each trip. You'll also need a coiled lighting cable to connect the motorhome to the towed vehicle.

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.
