Abstract
A valve in conjunction with an actuator has a valve position indicator coupled to the actuator. The valve position indicator has an indicator cover mounted over an indicator mounting surface, an array of LED lights arranged on the indicator mounting surface, and a mirror mounted internal and concentric to the indicator cover. A sensor in communication with the actuator and the plurality of LED lights communicates the position of the valve to the plurality of LED lights. The plurality of LED lights may illuminate to indicate an incremental degree that the valve is open, if any, and/or indicate by color the direction that the opening (or respective closing) of the valve is changing. In another embodiment with or without the mirror equiangular spaced single points of light each have one high intensity LED oriented to emit light horizontally and one high intensity LED oriented to emit light vertically.
