PRODUCT DESCRIPTION

Roadmaster Single Hy-Power Diode

Item 38188 | MFR# 790

790 Hy-Power Diode Single

Diodes are used to tie into the towed vehicles 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 vehicles taillights - preventing electrical feedback and the damage it can causes to the towed vehicles dashboard electronics.

If you are using a diode, why not the best!

Roadmaster's Hy-Power Diodes have a heavy-duty, anodized aluminum heat sink, and each diode is protected against the elements. All components are housed inside an epoxy-sealed, anodized aluminum case.

Four-pack required for most vehicles. Includes a detailed wiring diagram.
