Product details

The Roadmaster Hy-Power Diodes provide a dependable, high-quality solution for safely connecting a towed vehicle’s lighting system to your RV. Designed to prevent electrical backfeed, these diodes ensure that current flows in only one direction—protecting sensitive electronics in both the RV and the towed vehicle from potential damage. Without diodes, power from one system can travel backward into another, risking failure of lighting components or costly computer module damage. The Hy-Power Diodes eliminate this risk by delivering a controlled, isolated connection that allows your RV to operate the towed vehicle’s brake lights, tail lights, and turn signals safely and efficiently. Each diode is rated for 85 amps of continuous load, providing superior electrical capacity for modern towing setups. The heavy-duty aluminum heat sink design effectively dissipates heat, ensuring consistent performance and preventing overheating even during extended use. Each diode is also fully sealed in epoxy within a corrosion-resistant aluminum housing to block out moisture, dirt, and road debris, guaranteeing long-term durability in all weather conditions. Engineered and tested to meet Roadmaster’s rigorous quality standards, the Hy-Power Diodes offer a simple, professional-grade solution that enhances towing safety and reliability while preserving the integrity of your vehicle’s electrical systems.
