Abstract
Abstract To minimize wind resistance in streamlined vehicles, headlights are mounted at a fixed angle with their frontal lenses flush and parallel to the sloping body surface. Light is reflected at the required angle and intensity onto the roadway by a system of reflective spaced slats positioned near and rearwardly of the headlight lens and well forwardly of the parabolic headlight reflector. The reflective slats may be contained in a fabricated assembly or may be embodied in a unitized molded structure. The system is compatible with incandescent and halogen light sources and with standard adjustable headlight mounting structures on vehicles.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
125 words
A headlight for streamlined vehicles comprising in combination a sloping upper forward vehicle surface sloping forwardly and downwardly at an acute angle to the horizontal, a headlight reflector body portion including an internal illumination source and a frontal lens secured to the reflector body portion, the headlight being mounted with its optical axis substantially normal to said sloping surface and said frontal lens substantially flush therewith, and light deflector means held within the headlight rearwardly of the frontal lens and deflecting light rays from the optical axis of the headlight through the frontal lens and onto a roadway ahead of the vehicle on which the headlight is mounted at a required angle near the horizontal and in a required light pattern with proper light intensity.
Claim 2
Dependent Claim
125 words
