Abstract: A turn signal device, according to the present invention, for use on a vehicle having a turn signal, includes a human operated signal initiation device, at least one flasher; and at least one delay device. The at least one flasher and the at least one delay device are connected in a circuit which is responsive to the human operated signal initiation device. The vehicle turn signal is responsive to the circuit, and the circuit causes the vehicle turn signal to operate in a manner easily distinguishable from a conventional turn signal. In one arrangement, the circuit causes the vehicle turn signal to operate in a combination of long and short light signals. In a similar arrangement, the circuit causes the vehicle turn signal to operate in a combination of long and short light signals and a combination of long and short delays between the light signals. In general, the circuit causes the vehicle turn signal to operate in a series of light signals and delays.
