ABSTRACT:
A lighting system for a towed off-highway vehicle has a left and right hazard warning lamps that flash in unison when the vehicle is not turning. When the vehicle is turning, the hazard warning lamp on the side of the turn flashes, while the other hazard warning lamp is illuminated steadily. Left and right turn indicator lamps are operated by a control circuit that receives signals which operate the hazard warning lamps. The control circuit responds to those signals by rendering the turn indicator lamps inactive when the vehicle is not turning, and operates the left and right turn indicator lamps in the same manner as the left and right hazard warning lamps, respectively, when the vehicle is turning.
