The Norselight DM60 signalling lantern fulfils the requirements and is fully approved to the MED Regulations and SOLAS, which states that “all ships of over 150 tons gross tonnage, when engaged on International voyages, shall have onboard an efficient daylight signalling lamp which shall not be solely dependent upon the ship’s main source of electrical power.” The 127mm (5”) handheld signalling light can be used on all vessels, for ship to ship signalling using Morse Code. The light is of aluminium, lightweight And robust construction and is fully waterproofed. If desired this unit can be used as a spotlight if the signalling trigger and lamp switch are both left on. The Norselight DM60 Signalling Lantern is approved by the UK Maritime & Coastguard Agency (MCA.) Light reduction and coloured filters provide control light output as required. Tubular and V sights are fitted as standard. DM60 provides a handle mounted switch to operate the lantern. Signals are made by triggering the tubular shutter system which interrupts the light from the reflector.
