I live near a major airport and see commercial planes with huge front headlights shining in the night sky. What could they be good for way up in the sky, though? I get that when they are taking off/landing headlights are necessary. Why not give them lights like a boat, with a green in front and a red in back?
I don’t think the headlights are different colors or blink.
In many general aviation planes, they have a wig-wam setting that alternatively flashes the landing lights during the day.
