Stern lights are white and shine aft and 67.5Â° forward on each side. (Thus, the sidelights and stern light create a full circle of light.) All-round lights are white and shine through 360Â°. Masthead lights are white and shine from 112.5Â° on the port side through dead ahead to 112.5Â° on the starboard side.
