Navigation Light · Signaling & Visual
Den Haan Rotterdam DHR70N All-Round Green — Signaling & Visual. As a Navigation Light, it is normally installed at the vessel position required by the approved navigation-light arrangement with supply and monitoring connected to the bridge or distribution system. In that role, its primary purpose is to display the prescribed visual indication for vessel aspect, status or operation. Navigation-light variants differ in colour, sector and certified range, so the installed position and optical specification must match the vessel's approved arrangement. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
