  • Diodes used to tie into the towed vehicles brake light, running light and turn signal wiring
  • Hy-Power Diode allow motor homes or RVs to power the lights on the tow vehicle without power feedback
  • 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
  • Package Included: 1PC Hy-Power Diode, 3 PCS Wire Connectors, 1 PC Double-sided Tape

Before you order
  • Confirm the part number, position, dimensions, and connector details shown on this page.

    Working great, I used for a set of auxiliary reverse lights on the truck. They work off the factory reverse lights and a switch both. Now when I use the switch, I am not backfeeding in to the reverse light circuit.

    Was adapting a remote for a winch to a dump trailer. All the info said to get two diodes to split signal. Saw these and figured to give them a try because they would make wiring easier and they did the trick. Made wiring so easy. Would recommend them for sure.

    To diodes packaged in a cute little heat sink. Makes for a clean install. A pic of the product and a pen cap is included to get a sense of the size.The only thing I will knock off a star for is that the tape is not heat conductive, just your typical very high bond strength double sided tape.

    I needed a way to block power from my reverse backup lights so I could power switched flashing warning lights. The Diode kept power from back flowing from this setup. Now when I flip the switch on for the flashing lights, I am not back feeding in to the reverse light circuit. The Diode is only about 1 inch X 1.25 inch and looks to be very well sealed but it has no listing for being waterproof.

    Prevents back feeding in a 2 source single output circuit. I question the 2 sided tape, if it gets hot enough to be have a built in heat sink, won’t it melt the tape? My circuit is not continuous, so I don’t expect much heat build up, but something to keep in mind.

    I’m using this to isolate 2 batteries from each other in an RC airplane. It works perfectly. See the picture, the negatives are common and the positives are separated by the diode: this keeps one battery from trying to charge the other and allows either battery to power the plane. Didn’t get hot with 9v during testing, and the airplane runs on 7.6V so I’m pleased.
