CA 2060703

A lens is disclosed for use on automotive vehicles and which forms part of lamp assemblies used on the rear, front or side surfaces thereof. The lens utilizes a combination of optical elements and reflex elements interspersed therewith, the density of the reflex elements relative to the optic elements being graduated in selected areas of the lens surface, for example from the stop or brake light area of the lens through the "running light" area to a fog area. One form of the invention has the optic elements and the reflex elements on a single lens surface and, in another embodiment, the optic elements of the lens are located on one lens surface and the reflex elements are located in juxtaposition outwardly thereof on a second lens surface and spaced from one another so that the reflex elements are axially interspersed between the optic elements. The method of manufacturing both forms of lenses is also disclosed.
