What part of an aircraft is identified by a white navigation light?

A white navigation light is specifically used to identify the tail of an aircraft. This light serves to increase the visibility of the aircraft from the rear, allowing other aircraft and ground personnel to recognize its position and orientation. In aviation lighting conventions, each color of navigation light has a specific location and purpose, with red lights typically found on the left wing and green lights on the right wing for lateral identification, while white lights are standardized for the tail. This color-coding is vital for safety and helps pilots maintain spatial awareness, especially in low visibility situations or when operating near other aircraft.
