ABSTRACT:
An improved suction cup made of a light transmissive material is provided having a head and a cup portion a concave interior surface adapted to contact a window and an exterior surface opposite said interior surface. A ridge of material is provided along the outer portion of the exterior surface, so that, when the suction cup is in a sealing position, the ridge of material is generally parallel to the mounted surface. In such an arrangement, light passing through the ridge of material continues in a straight path and does not converge at a focal point. Alternatively, surface deformations, such as grooves, circular ridges, dimples, and roughing, may be provided on the exterior surface of the suction cup. These surface deformations diffuse the light passing therethrough, preventing all of the light from converging at a focal point.
