Trailer control device

Trailer control devices are control devices which partly or fully energize the lighting of the trailer. The control device and the trailer’s lights are fed by clamp 30 (Steady plus). If a vehicle does not have Check-control, the flasher as well as the rear fog light is lead across the control device to minimize the load on the vehicle supply system. If a vehicle does have Check-control, the complete trailer lighting is fed by the control device (clamp 30). In such a case, an exchange of the Flasher unit is not necessary.
