An RF controlled lighting system that activates lights in adjacent spaces when a person walks into a first space and then traverses the spaces in sequence. A detection device senses the entry of a person into a first space controlled by the system. A micro-controller activates the lights in that space for immediate light and in the adjacent spaces in preparation for the person to traverse the spaces in either direction from the origin space. As the person traverses the contiguous spaces, controllers in each space sense the person's presence and communicate by RF signals to activate lights along the person's path. The controllers extinguish their lights a predetermined time after the person passes or no one enters a space.
