Details: This poster shows a lighthouse surrounded by rough seas. At the bottom it says 'Stormwatch Light'.
An aid for navigation and pilotage at sea, a lighthouse is a tower building or framework sending out light from a system of lamps and lenses or, in older times, from a fire. Lighthouses are used to mark dangerous coastlines, hazardous shoals away from the coast, and safe entries to harbors. Lighthouses are often interpreted in dreams as beacons of truth.
