This mod creates illuminated versions of entities made available by the mods "Creative Mod" (https://mods.factorio.com/mod/creative-mod) and "Editor Extensions" (https://mods.factorio.com/mod/EditorExtensions ) and makes them available during the standard game, even without enabling creative mode in the game.
I believe that these entities should not appear in the crafting menu or anywhere else unless I activate the creative mode!
