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. In a preferred form, wherein the circuit causes the vehicle turn signal to operate in a repeated series of two short light signals followed by one long light signal, with short delays after the short light signals and a long delay after the long light signal. Such a signal represents the letter "U" in Morse Code. A similar code could be used for a slow-to-stop signal. In general, the U-turn signal would be on the front and rear driver side turn signal and the slow-to-stop or pull-over-to-stop signal would be on the front and rear passenger side. In one particular embodiment, the at least one flasher comprises two short flashers and one long flasher in series. In one such embodiment, the at least one delay device comprises a short delay device in series with and after each of the two short flashers and a long delay device after the one long flasher. Normally, the long flasher is at least twice as long as a short flasher and the long delay device delays at least twice as long as a short delay device.
