By law, a towed vehicle's turn signals, running lights and brake lights must mimic the motorhome's. There are three ways to accomplish this:

  1. A system of diodes that links the car's wiring system directly to the motorhome's.
  2. An internal, but separate system that replaces the taillight bulbs in the towed vehicle with independent plugs and sockets.
  3. An external tow light kit, such as magnetic towing lights, that sit on the towed vehicle.
