Abstract: A system for illuminating parts of an aircraft, such as a helicopter, including three low-intensity position lights (10) mounted on the aircraft, with two of the position lights mounted in a forward location and spaced laterally from the center of the aircraft and a third position light mounted in an aft location centrally positioned on the aircraft. The three position lights provide a triangular light formation that indicates the position of the aircraft during tactical, covert operations. The position lights include a chemiluminescent light source (12) and a housing (22) for carrying the chemiluminescent light source. Each housing is secured to a part of the aircraft by means of a bracket (52) and a pair of band clamps (60). The chemiluminescent light source is visible from within the housing within a limited range of the aircraft. Preferably, the chemiluminescent light source creates an infrared light that is detectable by means of night vision goggles worn by pilots of nearby flying aircraft.
