Abstract

See full text

An apparatus within a vehicle including a plurality of high beams in electrical communication with an automatic circuit to direct voltage to each associated high beam, wherein a photo-transistor is arranged in parallel circuitry to a relay coil and resistor, with the junction transistor arranged to interface between the first and the second parallel circuit, including the photo-transistor and adjustable resistor respectively. A modified detector circuit includes a second resistor in series with the resistor, and a third resistor in parallel relationship to the relay coil to effect a time delay in actuation of the high beam members of the vehicle. A third junction transistor is arranged in a third circuit parallel to the first and second circuit to direct current to the respective high beam for increased sensitivity relative to the incoming light source from a remote vehicle.
