Abstract

898,150. Photo-electric control of vehicle lighting. GRAZIANO, M. July 26, 1960 [June 1, 1960], No. 25957/60. Drawings to Specification. Class 40(3). In a vehicle light control system current to the lights is switched by the contacts of an electromagnetic relay in accordance with the ambient illumination of a photo-resistor which biases a transistor connected as an emitter follower to supply current to the relay coil.
