Abstract
The present disclosure provides a directionally filtered indicator light, wherein a directional filter is applied to a light source that is controlled to emit light when a condition or series of conditions are met. The directional filter, in turn, regulates the transmission of light from the light source so that a first group of individuals, located within a viewing angle, are the only individuals able to see the transmitted light. In one example, the directionally filtered indicator light of the present disclosure allows an indicator light on the interior of a passenger aircraft to be viewed from outside the aircraft in direct sunlight while substantially eliminating the presence of transmitted light from a passenger seating area.
