There’s nothing too complicated or tricky about the running lights. These lights are tied to the shrouds on either side fo the fore mast, and help to keep the ship noticeable in low light conditions.
The running lights from this period were lanterns, set into a back board that was painted red or green (depending on the side).
The Model Shipways Bluenose kit provides the lanterns as cast metal pieces, so those were cleaned up and painted.
The boards were made from 3/64″ thick basswood strips. One large piece forms the back, while two smaller pieces form the side and bottom of the ‘shelf’. These pieces were glued together, sanded, and painted.
The port running light was painted red, while the starboard running light was painted green. I made the edges and backs of each board black.
The running lights are then lashed onto the shrouds on either side.
