Abstract
An aircraft position light employs selected colored LEDs to produce a white appearing warning light with a reduced light component in the amplification spectrum of night vision imaging equipment. A combination of amber and cyan LEDs are selected to produce approximately three amber flux units for every cyan flux unit resulting in a white composite light. Both of the selected LEDs have dominant wavelengths of less than 600 nm.
