Diffused lighting camouflage was a form of active camouflage using counter-illumination to enable a ship to match its background, the night sky, that was tested by the Royal Canadian Navy on corvettes during World War II. The principle was discovered by a Canadian professor, Edmund Godfrey Burr, in 1940.
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.

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 ...
"Diffused lighting camouflage" was trialled by Canada's National Research Council during the Second World War. It involved projecting light on to the sides of ships to match the faint glow of the night sky, requiring awkward external platforms to support the lamps. [ 105 ]
In the diffused lighting camouflage project, the Royal Canadian Navy experimented with variable counter-illumination camouflage to match horizon light levels and minimize ships' silhouettes during prolonged arctic twilight. During the experiments, one side of the test ship was faintly illuminated by projectors mounted outboard.
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 ]
"So for Bud Light or brands like Bud Light who say, 'Oh, we didn't mean to offend you; sorry, we'll take a step backward to sit in the middle, not being on either side,' both sides go, 'Meh, no ...
To solve this problem, in 1943 the U.S. Navy, following the Canadian diffused lighting camouflage trials on warships, conducted secret experiments on counter-illumination in the Yehudi lights project. Sealed beam lights were mounted on the leading edge of the wing of a Grumman TBM-3D Avenger, and around its engine cowling, with the lamps facing ...
