Roadmaster Diode Hy-Power 1 Pack 790

Single Hy-Power Diode

Diodes are used to tie into the towed vehicle’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 — preventing electrical feedback and the damage it can cause to the towed vehicle’s dashboard electronics. ROADMASTER’s Hy-Power diodes have a heavy-duty, anodized aluminum heat sink, and each diode is protected against the elements. Four-pack required for most vehicles. Includes detailed wiring instructions.
