So you can tell if it's coming toward you or going away from you at night.
The RED light is mounted on the Right wing. The GREEN light is mounted on the Left wing. So if you see a plane at night and you see the Green light, then that means you are looking at his LEFT wing and he is moving to your Left.
I believe the use of colored lights may have originated with ships.
Why is this necessary? Can't you tell which direction a plane is going by following the direction of the lights?
The answer is No, not always.
If you are flying in a fast jet and see the lights of a plane moving from your Left to the your Right, it could be due to the fact you are flying faster than the other plane or you are in a slight turn. He could actually be flying in the opposite direction than what it appears. The colored lights help determine his direction.

Do aircraft wings move up and down?
Aircraft wings can move up and down as part of the normal operation of the aircraft. This movement helps to control the flight of the aircraft by adjusting the lift and drag forces acting on the wings. The wings can also move as part of the aircraft's flaps and slats system to change the wing's shape for takeoff and landing.

How does the propeller on a light aircraft make the move?
The blades on the propeller are angled in such a way that, while they are turning, they push air backwards towards the tail of the aircraft. This 'pulls' the aircraft forwards - and the air flowing over the wings lifts the plane into the air.
