Abstract
Abstract When a vehicle turns to either the right or left, a signal light must be lit indicating such a turn. This invention provides a means whereby the signal light (either right or left) is turned on by the movement of the steering wheel. Movement of the steering wheel will automatically close a switch and turn on a signal light indicating to another vehicle that the one vehicle is about to execute a turn.
