What color is the tail position light on an aircraft?

The tail position light on an aircraft is white. This light serves an important function by indicating the orientation of the aircraft to other pilots and air traffic control personnel. It is part of a system of lights that allows for safe visual identification, particularly during night operations or in poor visibility conditions.

The colors of the various position lights on an aircraft are standardized: the left wing light is red, the right wing light is green, and the tail position light at the rear is white. This color coding provides uniformity across the aviation industry, which enhances safety by enabling pilots to quickly identify the direction an aircraft is facing. In this context, the white tail light complements the red and green lights on the wings, completing the triangle necessary for awareness of the aircraft's position in the sky.
