Insignia indicating the department to which an officer belongs are worn on each side of the collar, a gold anchor for deck officers (corresponding to Line officers in the Navy) and a gold three-bladed propeller for Engineer Officers.
The white uniform is similar in style and design to the blue uniform, the braid being white and the insignia on the coat collar of gilt metal.
The Overcoat for Officers is double-breasted, made of dark blue cloth, extending to three inches below the knee, with two rows of black flat buttons down the front, six in each row and a wide rolling collar. It bears no stripes or insignia.
Quartermasters and machinists wear a blue uniform consisting of a double-breasted sack coat of dark blue cloth, with five gilt buttons on each side, turn-down collar and lapels, two side pockets with flaps; plain dark blue cloth trousers; and a cap of the same pattern as that worn by officers, but having a black patent leather chin strap, and the letters “U. S. L. H. S.” embroidered in gold around the base of the silver lighthouse insignia instead of the gold wreath on the front of the officers’ cap.
The insignia indicating the rank, worn on each sleeve midway between the shoulder seam and the elbow, consist of a ship’s steering wheel embroidered in white for quartermaster and a three-bladed propeller embroidered in red for machinist.
