Yehudi lights

Yehudi Lights on Grumman TBM-3D Avenger
Yehudi lights were tested in B-24 Liberators from 1943.
Yehudi Lights raise the average brightness of a Grumman Avenger from a dark shape to the same as the night sky.

Yehudi lights are lamps placed on the underside or wing leading edge of an aircraft to raise the aircraft's luminance to the average brightness of the sky, a form of active camouflage using counter-illumination. They were intended to disguise the aircraft by preventing it from appearing as a dark object against the sky.
