Abstract: A CHMSL (16) or other lighting system feature of an automobile (10) includes a feature for presenting personal expressions in the form of words or symbols but is automatically deactivated when the regular vehicle lighting system is in use. The personal expression is fixed in a tangible medium by way of phosphor-coated indicia (34) placed within a UV impervious housing (18). A secondary UV light source (36) selectively energizes the phosphor-coated indicia (34) so that the irradiated material glows and is visible through a light transmissive screen (20). The light transmissive screen (20) is provided with a UV blocking agent so that harmful UV rays do not escape the housing (18). The phosphor-coated indicia (34) can be mounted on a removable transparent plate (30), on light dispersion optics (24, 26), or on the inner face of the light transmissive screen (20).

Abstract: A reduced glare projector style headlight assembly (10) comprises a light source (14), a reflector (12) and an optical lens (18). An opaque mask (16) is positioned between the lens (18) and the reflector (12) for creating an upper shadow region in the focused beam pattern (28) to shield on-coming traffic. The mask (16) includes a transition region (32) proximate its top edge (22) for allowing a limited amount of projected light to pass through the mask (16), into the upper shadow region in the focused beam pattern (28). In several embodiments, the mask (16) is applied or otherwise affixed to a transparent substrate (20) which also supports the transition region (32). To combat undesirable chromatic effects, a color filter (38) can be positioned in the light path (26) for disrupting selective wavelengths of light energy. As alternative approaches, the transparent substrate (20) and/or the lens (18?) can be doped with a color filtering material or composition.
