Roadmaster Hy-Power Diodes
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 car's electrical components.

Easy to install in-line of your towed vehicle. Use your toad's own lighting and eliminate magnet sets or additional lighting installs. As easy as wiring a trailer. Make towing your toad as simple as possible. You owe it to yourself.13170
