Abstract

1,077,515. Lamp failure alarms. J. H. D. WILLIAMSON, D. V. MORRIS, and W. W. WILSON. Dec. 3, 1964 [Oct. 29, 1964], No. 49262/64. Heading G4N [Also in Division G1] The driver of a motor vehicle is apprised of the failure of one of the vehicle lamps by an alarm signal actuated by means sensitive to the light from the lamp. A photo-conductive cell 20 is located behind a gap in the reflector coating of the lamp, Fig. 1 (not shown), so as to receive light from the filament of the lamp. The cell 20 is connected in a conventional transistor trigger circuit, Fig. 2 (not shown), to operate a warning lamp 30 when the vehicle lamp fails.
