Navigation lights on an aircraft include which colors?

Navigation lights on an aircraft are essential for ensuring visibility and communication with other aircraft, especially during night operations or in poor weather conditions. The correct combination of navigation light colors includes red and green sidelights along with an all-round white light.

The red light is located on the left (port) side of the aircraft, while the green light is on the right (starboard) side. This color scheme allows pilots to determine the orientation and direction of other aircraft; when approaching another aircraft, seeing the red light indicates that it is on your left side, while the green light signifies it's on the right. The all-round white light is typically mounted at the tail of the aircraft and is used to indicate the aircraft’s position to other aircraft from behind.

Understanding this color coding is crucial for safety and efficient aerial navigation, especially in crowded airspace where visual signals help prevent collisions. The incorrect options misrepresent either the colors or the arrangement of these vital safety features.
