Ive been thinking a small lantern as in the Animated Series could work as a tool. It would add to the classic Batman stereotype and it would pay homage to the various films and the Animated Series themselves. It would look and work pretty good and would give us this retro detective Batman. For example in the sewers or in an abandoned dark warehouse. We could use the small lantern to light up our way and see our surroundings in the dark. This tool could just be available for use in certain areas and in certain lighting conditions (having it as a gadget could work also but im not sure). What do you think fans and Rocksteady? It could also work in Scarecrow nightmare sequences or in places where we should feel vulnerable or fear
With the new lighting system it could look and work pretty nice. The light could even light up some dust/air particles in the way. It would look so good.
