Use your towed vehicles lights while keeping it's electrical system protected.
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 car — preventing electrical feedback and the damage it can cause to the towed vehicles's dashboard electronics.
If you’re using a diode, why not use 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.
By preventing electrical feedback, ROADMASTER's HY-POWER diodes allow you to splice into the towed car's wiring system without damaging expensive electronic dash components. Reduces wiring hassles. Trouble-free operation.
Four-pack required for most vehicles. Includes (3) three HY-POWER diodes and detailed wiring instructions.
