If the aircraft is in flight, a steady green light signal from the control tower means cleared to land. If the aircraft is on the ground, it means cleared for takeoff. If the light is aimed at ground vehicles or foot traffic, steady green means cleared to cross the runway, or proceed.
For an aircraft on the ground, it means that you are cleared for taxi. For an aircraft in flight, you must return for landing or go around and attempt landing again.
