The LED Visual Approach Slope Indicator (VASI) is used to guide aircraft to approach the runway at an appropriate altitude. It is specially designed to accommodate the helicopter's steep angles of descent and deliberate speeds.
There are three Colors which to show three wide horizontal beams in different colored light. And it is projected in fan shaped array into the incoming flight pattern. The top beam is yellow which indicates a too high altitude of approach; The center beam is green which is the correct altitude; The lower beam is red which indicates a too low altitude.
By staying within the green light beam that is correct altitude.
