What color are the navigation lights on the wing tips?

The navigation lights on the wing tips of an aircraft serve a crucial purpose in ensuring visibility and safety during flight. The correct arrangement is that the left wing tip is fitted with a red light, and the right wing tip is equipped with a green light. This color scheme is standardized as per aviation regulations.

The reason for this specific color arrangement is to help pilots and ground crew easily identify the orientation of an aircraft at night or in low visibility conditions. When two aircraft see each other in the air, they can determine their relative headings based on the position of these lights. For example, if a pilot sees a red light on the left side, they know that the other aircraft is off their right side and moving toward them, creating important situational awareness.

The other options listed do not conform to the established color codes for aircraft navigation lights, reinforcing the importance of the correct red and green configuration.
