  • Patent number: 4495552
    Abstract: A lamp is provided for use on vehicles, which lamp is of the type wherein the light rays are projected forwardly in a predetermined pattern. The predetermined pattern is generated by virtue of a generally continuous grid of the reflector within the lamp, and the lamp does not need a prismatic lens system at the location where the light rays eminate from the lamp.

  • Patent number: 4331382
    Abstract: Provided is an improved rear view or rear vision mirror for passenger automobiles, vans and like vehicles, exclusive of buses or trucks larger than pick-up trucks, which mirror affords a wide-angle view well beyond the statutory requirement that outside mirrors give a view of the side of the vehicle through a 10.degree. angle beyond such side of the vehicle to the extent that the image covers the so-called "blind spot" beyond the 10.degree. view path. The improved mirror avoids the use of spherical reflective surfaces and consists essentially of a single substantially planar reflective surface and a single contoured reflective surface that is a generally convex cylindrically contoured surface having a radius of curvature within a critical range of values.
