Turn signal/brake light converters for towed vehicles

摘要

A converter circuit connected between the signal light control system of a towing vehicle and the turn signal and brake lamps of a towed farm implement discriminates between braking signals and turn signals appearing at the same pin positions of a connector receptacle by timing the duration of the signals. In a second embodiment providing for enhanced lighting of farm implements when traveling on public roads, latching relays establish circuits for flashing the brake lamp in the direction of turn. A switch may be provided to enable the enhanced lighting when the towing vehicle is a tractor, or disable the enhanced lighting and permit the implement turn signal and brake lights to mimic the operation of the turn signal and lights on a truck when the towing vehicle is a truck.
