Abstract
A mirror assembly including a semitransparent mirror which passes about 1% to about 8% of a broad band of visible light, and which reflects about 35% to about 58% of a broad band of visible light. A light assembly is positioned adjacent to the semitransparent mirror and emits visible light which is passed by the semitransparent mirror. The luminous intensity of the mirror assembly being about 2 to about 20 candelas.
