2-mile, 360° visibility, for boats up to 39.4' in length. Since all-round lights must be at least one meter (39-3/8") above the sidelights, some boats require a long light pole. It has all the same features as the Articulating model 533042 plus one great advantage - the removable pole folds in half for easy stowage. 9 watt wedge-base lamp. 2-pin locking collar pole.
