US Patent 7325950 Headlight antiglare device

An antiglare device comprises a housing for coupling to a headlight of a vehicle. Surfaces of the housing which face a passenger side of the vehicle are reflective to encourage reflection of light away from oncoming traffic while surfaces of the housing facing towards the driver side of the vehicle are preferably non-reflective to reduce the amount of light reflected towards oncoming traffic. Plates may be supported within the housing through which the light passes in which the plates similarly include reflective and non-reflective surface. The plates may be pivotal between a high beam position parallel to the direction of light projected through the housing and a low beam position in which the plates are deflected in the direction in which the reflective surfaces face towards the passenger side. The plates may instead be horizontal in the high beam position and deflected downwardly in the low beam positions.
