<p>HMS <i>Largs</i> was used in 1942 for secret trials of a Canadian invention, <a href="Diffused_lighting_camouflage" title="Diffused lighting camouflage">diffused lighting camouflage</a>. This used dimmable lamps for <a href="Counter-illumination" title="Counter-illumination">counter-illumination</a>, <a href="Camouflage" title="Camouflage">camouflage</a> by bringing the brightness of the ship's superstructure to the same as the night sky. The system of 60 lamps reduced the distance at which a ship could be seen from a surfaced submarine by 25% using binoculars, or by 33% using the naked eye. It worked best on clear moonless nights, at best preventing <i>Largs</i> from being seen until it closed to 2,250 yards (2,060&nbsp;m) when counter-illuminated, compared to 5,250 yards (4,800&nbsp;m) unlighted, a 57% reduction in range. However, with the development of marine radar, the system was not put into service.<sup id="cite_ref-NavalMuseumQuebec_6-0" class="reference"><a href="#cite_note-NavalMuseumQuebec-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

After the end of the war she was handed back to France, and served for nineteen years. She was sold off to a private company from Greece in 1964 as a cruise ship, and given the name MV <i>Pleias</i>. She was scrapped in 1968.
