ABSTRACT:
In preferred embodiment, a mirror having selectively lightable indicia, including: a substrate of a substantially optically clear material; an optically reflective, optical filter layer disposed on a rear surface of the substrate, the optical filter layer providing at least one relatively narrow bandpass through which light can pass; a plurality of light sources disposed behind the optical filter layer, the plurality of light sources producing light in at least one relatively narrow range of frequencies substantially coincident with the at least one relatively narrow bandpass, such that light from the plurality of light sources can pass through the optical filter and thence through the substrate; and the optical filter layer reflecting, through the substrate, essentially all incident ambient light.
