ABSTRACT:
A fiber optic finger light for use by pilots, navigators and aircraft crew during night flying, which fiber optic finger light includes, in a most preferred embodiment, green and red light-omitting diodes (LED) mounted in a housing adapted for strapping to one hand and operated by a 3-position switch. A lens is mounted forwardly of each of the light-emitting diodes and serves to selectively focus light from the light-emitting diodes on one end of one of a pair of light-transmitting fibers which extend through the housing and project from the housing in a flexible duplex fiber optic cable. The light housing is strapped to the wrist and the fiber optic duplex cable is strapped to a finger, such that red or green light emitted from the LED at the opposite end of the optic fiber by manipulation of the switch, may be focused on charts, instruments check lists and the like, in the aircraft.
