Woodland Scenics Just Plug lights can be used in more than just train buildings. Claude Zeringue used them to light his scratch-built 1/35 flak tower.
He used both the red and the white lights to illuminate the interior. The white lights were for daytime operation; the red lights were for night time operation. Red lights didn’t interfere with the soldier’s night vision.
He also built a search light using one of the white LEDs.
