Abstract
A radiant energy transmitter for use with a motor vehicle wherein operation of the triggered radiant energy device of the transmitter is altered via an operation altering circuit portion when an alteration initiating switch assumes its alteration mode. Such alteration mode is automatically assumed when the operator carries out an action that is normally done after the motor vehicle is stopped. The operation altering circuit portion continues the altered operation even though the alteration mode of the alteration altering switch is subsequently discontinued.
