What color is used for the right position light on an aircraft?

The right position light on an aircraft is green. This color coding is standardized to enhance safety and recognition of an aircraft's orientation during both day and night operations. The green light indicates the right side of the aircraft, while the left side is indicated by a red light.

This color distinction is critical for other pilots to determine the aircraft's direction and position relative to their own. In practice, when pilots observe an aircraft at night, seeing a green light means that the aircraft is approaching from the right side, which can help in making precise navigation and separation decisions. Recognizing these light colors is an essential part of understanding aircraft operation and maintaining safety within the airspace.
