An exit sign comprising a housing and a plurality of red and green color
LEDs having the capability of being selectively activated to produce
either red light or green light. The plurality of LEDs are mounted in a
mutual lighting association in the housing. A switch is manually operable
to selectively activate the plurality of red color LEDs to produce the
red light and in the alternative, to selectively activate of the
plurality of the green color LEDs to produce the green light. Means for
passing light from the selected red light or selected green light in the
form of indicia symbolizing an exit enables viewing by an observer, such
means include a stencil having four independent letters forming the word
EXIT. DC circuitry is in operative electrical connection with the
plurality of LEDs. A source of DC electrical power activates the DC
circuitry. The plurality of LEDs can be monochrome red LEDs and
monochrome green LEDs or in the alternative, the plurality of LEDs can be
bicolor LEDs having the capability of producing red light or green light.
Red light and green light can be simultaneously emitted so as to produce
yellow light. An emergency power backup battery is connected to the
plurality of color LEDS. Means for producing emergency light is optional.
