Hy-Power Diode allow motor homes or RVs to power the lights on the tow vehicle without power feedback
Diodes used to tie into the towed vehicles brake light, running light and turn signal wiring
Tail Light Isolating Diodes: Diodes only allow electrical current to flow in one direction, from the motorhome to towed vehicle's taillights; It prevents any electrical feedback and the damage it may cause to the electrical components
Replace Old/Broken Diode: Simple splicing into existing harness by just taking off the old spade connectors and replacing it
