1. A daytime headlight system comprising, in combination:

  • a pair of headlights mounted on a front of a vehicle, each headlight having a high beam light adapted to emit light with a first intensity upon the receipt of a predetermined voltage and a low beam light adapted to emit light with a second intensity lower than the first intensity upon the receipt of the predetermined voltage;

    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 and 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 adapted to supply the predetermined voltage upon the insertion of a key within an associated key hole and rotation thereof, wherein the ignition switch continues to supply the predetermined voltage only while the key is situated within the key hole; and

    relay means connected between the headlights, electrical system, and ignition switch, the relay means having a first mode of operation wherein the high beam lights are disconnected from the high beam terminal and further connected to the ignition switch in series for producing a light less than the first intensity only during the receipt of power from the ignition switch in combination with the lack of receipt of either beam signal by the vehicular electrical system, the relay means further having a second mode of operation wherein the high beam lights are disconnected from the ignition system and further connected to the high beam terminal in parallel for producing a light of the first intensity only during the receipt of the high beam signal by the vehicular electrical system.
