The water light must be attached to the ring life buoy by a 12-thread manila or equivalent synthetic lanyard not less than 1 meter (3 feet) nor more than 2 meters (6 feet) in length. The water light must be mounted on a bracket near the ring life buoy so that when the ring life buoy is cast loose, the water light will pull free of the bracket.
