This Dutch-made electric port side light is an elegant and functional example of an antique navigation lamp. The solid brass fixture is polished and lacquer finished to ensure a long-lasting shine. It is fitted with a red lens that designates port (left) side, and it can stand alone or hang. A green starboard (right) side light is also available (8311G/E). The manufacturer of this lamp, Den Haan Rotterdam (DHR), was founded in Rotterdam, Holland, in 1922. It began as a manufacturer of navigation and interior lighting for inland and seagoing vessels. All lamps, many of them replicas of old models, are handmade to commercial ship standards.
