ABSTRACT:
An emergency sign includes a body having a top, two spaced apart sides, and a bottom defining a cavity, a front cover having an inside surface and cut out portions extending through the cover forming indica, a light source disposed within the cavity, and a diffuser coupled to the cover and covering the indicia, the diffuser having cut away portions for permitting light from the light source to reflect off of the inside surface of the front cover. The diffuser may include pigment therein, which pigment is color matched to correspond to the wavelength of the light from the light source. The light source may include an array of LEDs where some of the LEDs are of a diffused type and some of the LEDs are of a unidirectional type.
