What are aircraft wingtip light colors?

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

Answer: (A)

Navigation lights on aircraft are there to show orientation to other pilots, especially in low visibility. The colors on the wingtips are fixed: red on the left wingtip and green on the right wingtip. This pairing provides a quick, unambiguous cue about which side of the aircraft you’re seeing and helps determine whether the plane is approaching, crossing, or moving away. The standard is international, so pilots everywhere read the same signals. There are white lights as well, mainly seen from the rear, but for the wingtips themselves the rule is red on the left and green on the right. Blue would not convey the necessary directional information, so the best answer is left wingtip red and right wingtip green.
