HC Deb 18 December 1941 vol 376 cc2089-90W
Miss Rathbone

asked the First Lord of the Admiralty whether arrangements have been made in the Navy, similar to those now adopted in the Mercantile Marine, to attach coloured electric lights to rafts and differently coloured lights to lifejackets for the purpose of facilitating the rescue of shipwrecked men?

Mr. Alexander

The arrangements for this purpose in the Royal Navy, though similar to, are different in certain respects from those in the Mercantile Marine. I consider it undesirable to make public the details.
