ABSTRACT:
A motor vehicle headlight which includes a reflector, a light source (e.g., tungsten halogen capsule) within the reflector and a lens secured across the reflector's forward opening and including thereon means for substantially preventing glare to an oncoming motorist during headlight operation. This preferred means for preventing glare comprises a quantity of masking material (e.g., an opaque coating containing a black pigment) located on the lower angular surfaces or portions thereof of a preselected number of lensing facets formed within an internal surface of the lens. Light is thus prevented from passing through these masked angular surfaces or portions thereof in a substantially upward direction from the headlight location, which passage could in turn cause said glare. In a specific embodiment, a small size headlight (e.g., having an overall height of only about two inches) is described, which, if used in combination with a similar small sized headlight, could be used to provide the low beam function or one-half of a total lighting assembly for use in the motor vehicle. Thus, a total of eight such small sized headlights would be used per vehicle.
