Abstract: A position indicator useful in determining the position of a rudder on a boat consists of apparatus and circuitry for causing a plurality of lights to light in such a way that all are on in a first color when the rudder is in a full port position, all are on in a second color when the rudder is in a full starboard position, and between full port and full starboard the lights change color and turn on and off into combinations indicative of the position of the rudder.
