Another type of light was made for towed artillery and towed mortars but I don't know what year they were introduced. Basically it is a metal disc painted white which hangs below a heavier piece of angled metal which would rest against the bottom of the towed item's barrel. A strap wraps around the barrel to keep the device in position. And the small convoy lamps shines onto the white disc to illuminate it when plugged in via a small window while the end with a red lens also illuminates. The cable has armoured braiding and is 15-20 feet long so it can reach the dash power socket on a carrier. This example is 1944 dated on the quick-release pattern webbing strap and drawings of this item are shown in my 4.2-inch towed mortar manual along with other mortar specific accessories.
