Roadmaster’s Hy-Power diodes keep your tow vehicle and trailer wired safely. A powder-coated aluminum heat sink dissipates the current each diode manages, while epoxy sealing protects against weathering.

Route brake, turn, and running-light circuits through these diodes to prevent feedback damage and control flow from motorhome to trailer lights only.

• 80 Amp rating per diode
• Heavy-duty aluminum heat sink with powder coating
