Abstract
An article (10) comprises a transparent material (42) having interior and exterior surfaces (44 and 46). A coating of paint (48) is applied to the exterior surface (46) of the transparent material (42). Indicia (12) are formed in the coating of paint (48) by a plurality of interrelated line segments (50). Each line segment (50) of the plurality of line segments (50) extends parallel to each other line segment (50). The article (10) further comprises a light source (40) actuatable for directing light against the interior surface (44) of the transparent material (42) and through the line segments (50) to illuminate the indicia (12). The indicia (12) are discernible from the coating of paint (48) when illuminated by the light source (40) and are indiscernible from the coating of paint (48) when not illuminated.
