What color are the navigation lights on the wingtips?

• A. The left wingtip is red and the right is green.
• B. The left wingtip is green and the right is red.
• C. Both wingtips are red.
• D. Both wingtips are green.

Answer: (A)

Navigation lights on aircraft are arranged to show orientation at night or in low visibility. The left wingtip carries a red light and the right wingtip a green light, so other pilots can quickly tell which side of the aircraft they’re looking at. This standard color pairing—red on the port (left) side and green on the starboard (right) side—helps determine direction and reduces collision risk. Having both wingtips the same color or reversed would remove that quick visual cue, which is why the red-left/green-right configuration is the correct one.
