An addressable illuminator is disclosed consisting of multiple optical sources used in combination with an electrical circuit so that different combinations of the optical sources can be energized without exceeding eye-safety limits. Operation of multiple optical sources may be proximate, which is eye-safe, regardless of the number of or which ones of the optical sources are energized and regardless of the position of observers. An illuminator with multiple optical sources remains eye-safe when there are single-point electrical failures, such as short circuits, in the driving circuit. Monitoring or a feedback loop for the output power is not required or necessary to control the distance of an observer in order to be eye-safe.
