The coloured lights on an airplane are primarily for navigation and visibility, consisting of red, green, and white lights.
Here's a breakdown:
- Red Light: Located on the left wingtip (also known as the port side).
- Green Light: Located on the right wingtip (also known as the starboard side).
- White Light: Located on the tail of the aircraft.
These lights, collectively known as navigation lights, help other pilots and air traffic control determine the aircraft's direction and orientation, especially during nighttime or low-visibility conditions. The configuration of red on the left and green on the right is a standard maritime and aviation convention for indicating direction. Many aircraft also have dual systems for these lights to provide redundancy in case of a bulb failure.
