ABSTRACT:
A daytime headlight system is provided including a pair of conventional headlights mounted on a front of a vehicle. Each headlight has a high beam light adapted to emit light with a first intensity upon the receipt of a predetermined voltage. A low beam light is adapted to emit light with a second intensity lower than the first intensity upon the receipt of the predetermined voltage. Also included is a vehicular electrical system having a low beam terminal adapted to supply the predetermined voltage upon the receipt of a low beam signal generated by a user controlled switch within a cab of the vehicle. Associated therewith is a high beam terminal adapted to supply the predetermined voltage upon the receipt of a high beam signal generated by the user controlled switch. An ignition switch provided to supply the predetermined voltage upon the insertion of a key within an associated key hole and rotation thereof. The ignition switch continues to supply the predetermined voltage only while the key is situated within the key hole. Next provided is a control mechanism to effect the emission of light from the high beam lights upon the receipt of the predetermined voltage from the ignition switch and the lack of receipt of the predetermined voltage from vehicular electrical system.
