Abstract
A position light (200) for use on an aircraft. The aircraft position light uses light sources (302) installed into an alignment fixture (304) which optionally carries away heat generated by the light sources. Light emitted by the light sources is directed into a first prism (308), which distributes and directs the light. A second prism (324) is used to further shape the pattern of the light. A lens (206) is installed over the position light (200) to protect it from the elements.
