Abstract
A reflective fog filter is comprised of a substantially flat white substrate upon which a translucent color filter is applied. A preferred embodiment comprises a blue translucent acetate filter applied to a bright white metallic substrate. The subject apparatus is placed on the dashboard and/or cowl of a motor vehicle with the filter side up. Ambient light striking the apparatus is filtered and reflected onto the windshield directly in the driver's field of view. The apparatus therefore uses ambient light to project a filter onto the windshield. Visibility of objects in fog and other conditions that scatter light is enhanced when light reflecting from the objects is viewed through that portion of the windshield onto which the filter is reflected.
