What color are the Formation Lights?

• A. Red
• B. Green
• C. Blue
• D. White

Answer: (B)

Formation lights are a subtle green illumination used during night formation flying to help pilots maintain position and spacing without overpowering night vision. The color green is chosen because it stands out against darkness and remains easily visible to pilots in the cockpit and from outside, while avoiding confusion with the standard red/green navigation lights on the wingtips. That’s why the Formation Lights are green. Red, blue, or white lights are associated with other aviation lighting functions and wouldn’t serve the same formation-visibility purpose.
