Diodes are perhaps the most common method of connecting lighting between your RV and flat towed vehicle. If you connect the lighting without diodes, the current from the RV can flow backwards through the car, damaging its computer. Similarly, if the lights of the towed vehicle are turned on while still connected to the RV, then the current from the towed car can destroy the RV's computer module. Roadmaster Diodes prevent electrical feedback to either vehicle. The diodes allow the RV to illuminate the towed vehicle's lights without any danger of damaging either vehicle. How do they do this? They only permit electrical current to flow in one direction - from the motorhome to the towed vehicle's taillights - and permit the towed vehicle's brake lights, running lights and turn signal wiring to connect to the motorhome.
