Which of the following statements correctly describes wingtip lights?

• A. Left wingtip red; right wingtip green
• B. Left wingtip green; right wingtip red
• C. Left wingtip blue; right wingtip red
• D. Left wingtip red; right wingtip blue

Answer: (A)

Wingtip navigation lights use a simple color code to show aircraft orientation: red on the left wingtip and green on the right wingtip. This standard helps other pilots determine which side of the aircraft is which, especially at night or in low visibility. The statement that describes the left wingtip as red and the right wingtip as green matches this international setup, so it’s the correct description. Swapping the colors would misrepresent orientation, and blue isn’t used for the standard wingtip navigation lights on civil aircraft. (There are white strobe lights at the wingtips as well, but those are separate from the colored navigation lights.)
