A directional indicator system for vehicles such as automobiles comprises a flasher unit and left hand and right hand marker lamps positioned on the vehicle. The flasher unit causes current to pulse through the marker lamps so that the marker lamps flash. Transmission of current to the marker lamps from the flasher unit is controlled by a timer circuit. The timer circuit includes switches that enables selection of one of the left hand and right hand marker lamps and then provide current to the selected left hand or right hand marker lamps for a predetermined duration. A plurality of timers can be provided and a plurality of time durations can be selected. The system can further comprise a complete turn shut-off switch that prematurely ends the operating duration of the timer circuit when a turn of sufficient radius is completed.
