The concept behind diffused lighting camouflage was to project light on to the sides of a ship, to make its brightness match its background. Projectors were mounted on temporary supports attached to the hull and the prototype was developed to include automatic control of brightness using a photocell. The concept was never put into production ...
The use of Yehudi lights to camouflage aircraft by matching their luminance with the background sky was developed, in part, by the US Navy's Project Yehudi from 1943 onwards, following pioneering experiments in the Canadian diffused lighting camouflage project for ships early in the Second World War. [3]
The first of these was the so-called diffused lighting camouflage tested on Canadian Navy corvettes including HMCS Rimouski. This was followed in the United States Army Air Forces with the airborne Yehudi lights project, and trials in ships of the Royal Navy and the US Navy. [11] The Yehudi lights project placed low-intensity blue lights on ...
Diffused lighting camouflage, in which visible light is projected on to the sides of ships to match the faint glow of the night sky, was trialled by Canada's National Research Council from 1941 onwards, and then by the Royal Navy, during the Second World War. Some 60 light projectors were mounted all around the hull and on the ships ...

On 22 January 1941 she took part in the Canadian Navy's first secret trial of diffused lighting camouflage, a technology for concealing ships from submarines at night. [12] She worked up and joined Halifax Force, but left on 23 May 1941 with the six other corvettes that were the nucleus of the new Newfoundland Escort Force (NEF).
Diffused lighting camouflage, a shipborne form of counter-illumination camouflage, was trialled by the Royal Canadian Navy from 1941 to 1943. The concept was followed up for aircraft by the Americans and the British: in 1945, a Grumman Avenger with Yehudi lights reached 3,000 yards (2,700 m) from a ship before being sighted.
