ABSTRACT:
A motor vehicle turn signal system has features to indicate lane changing. The system includes a flasher that supplies pulsated power to the conventional turn signal lever switch. Right and left push button switches are mounted to the steering wheel. Each button switch is linked to a relay coil. The relay coil, when energized, connects the flasher directly to the signal lights, bypassing the conventional turn signal lever switch. The connection between the flasher and the conventional turn signal lever switch is broken while the relay coil is energized. In one version, a transmitter mounted to the steering wheel transmits a signal to a receiver in the vehicle when a button switch is depressed.
