Abstract

The present invention provides a self-adjusting headlight system for vehicles to maintain proper forward vertical alignment of the headlight even when the vehicle is unevenly loaded in the front to rear direction. The system comprises a housing which is secured to the body of the vehicle. A headlight frame is provided, within which the headlight id mounted. The frame is mounted on a pivot secured to the housing, to pivot freely about a horizontal axis. The frame is balanced on the pivot so that the beam of the headlight is normally properly forwardly aligned. The balance means comprises a pendulum downwardly extending from the frame on an arm. A portion of the pendulum is attractive to magnetism. An electromagnet is secured to the car body and positioned in the vicinity of that portion of the pendulum so as, when actuated, to secure the pendulum and hence the headlight frame, in that particular relative position with respect to the car body. The electromagnet is actuable by a driver as required. When the electromagnet is actuated, the headlight frame is balanced on the pivot so that the headlights are properly positioned, in the vertical plane, and held in that position until the e…
