ABSTRACT:
An apparatus for use in the cockpit of an aircraft which provides sufficient illumination to read the cockpit display indicators, controls and charts but does not destroy the pilot's night vision. A casing, which is normally worn on the wrist of the pilot, contains a microencapsulated electroluminescent phosphorus lamp which provides illumination that will not affect the pilot's night vision. The lamp is powered by an inverter which is connected through a switch to a power supply, all of which are also contained within the case.
