Vehicle turn signal
First Claim
1. A directional indicator system for vehicles comprising:
- a flasher unit;
left hand marker lamps;
right hand marker lamps;
a first timer interconnected between the left hand marker lamps and the flasher unit and a second timer interconnected between the right hand marker lamps and the flasher unit, each of the first timer and the second timer being individually operated by a switch and the first timer and second timer each operating for a first predetermined time when operated by the switch, the flasher unit causing one of the left hand marker lamps and the right hand marker lamps to flash when one of the first timer and the second timer, respectively, is operated; and
a third timer and a fourth timer interconnected with each of the left hand marker lamps and the right hand marker lamps, respectively, the third timer and the fourth timer operating for a second predetermined time that is longer than the first predetermined time.

Abstract
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.

19. A directional indicator system for vehicles comprising:
-
a flasher unit; left hand marker lamps; right hand marker lamps; a timer circuit and a control switch circuit interconnected with each of the flasher unit, the left hand marker lamps and the right hand marker lamps, the control switch circuit and the timer circuit being constructed and arranged so that operation of the control switch circuit causes the timer circuit to selectively operate one of the left hand marker lamps and the right hand marker lamps to flash in response to the flash unit for a first predetermined time, wherein the switch circuit comprises a first pair of switches interconnected with the timer circuit, each of the first pair of switches operating a respective of the left hand marker lamps and the right hand marker lamps to flash in response to the flasher unit; and a timer reset circuit constructed and arranged so that the timer circuit is deactivated by operating each of the pair of switches substantially simultaneously. - View Dependent Claims (20)
