Hy-Power™ Diodes

Diodes are used to tie into the towed vehicles's brake light, running light and turn signal wiring, and connect it to the motorhome. Diodes permit electrical current to flow in only one direction — from the motorhome to the towed vehicle's taillights — preventing electrical feedback and the damage it can cause to both vehicles' electronics.

If you're using a diode, why not use the best? ROADMASTER's Hy-Power diodes have a heavy-duty aluminum heat sink, and each diode is protected against the elements — all components are housed inside an epoxy-sealed, powder-coated aluminum case.

Four-pack required for most vehicles. Includes detailed wiring instructions.

Park Light Diode

Problem: Electrical damage can occur to the towed vehicle if its headlights are turned on while still connected to the motorhome.
Solution: Use a Park Light Diode to stop any interaction between the two park light systems, preventing electrical feedback and electrical damage.


Note: the Park Light Diode will not replace Hy-Power diodes.
