First Claim
Patent Images
1. A lighting and observation installation for a motor vehicle which improves vehicle driver visibility during foggy weather conditions;
- said installation comprising;
motor vehicle fog lights having means for radiating polarized light over an area in front of a motor vehicle which supports said fog lights, and analyzer means positioned on said vehicle in a position interposed between a portion of the vehicle occupied by the eyes of a vehicle driver and said area in front of the motor vehicle, said analyzer means including means for controlling the relative amount of light reflected from objects in said area and from fog droplets in said area which reaches the driver'"'"''"'"'s eyes, wherein said analyzer means is mounted for rotatable movement in its plane to accommodate adjustment of the analyzer means by the driver so that the relative amounts of light reflected from objects and fog droplets can be readily varied by the driver for varying fog and road conditions to optomize the difference between the light reflected from the objects and the fog droplets.
