I can stop bugging the local Pinsiders now that I got a Shadow. I put two spotlights on the playfield and one on the Battlefield. The cone that goes on the spotlight was too much of a distraction for me on the Battlefield, so after trying a bunch of colors I went with a flexible/bendie LED in red. My reasoning for using red is probably way over the top, but it's kinda to create a mood like in a stage production. Like if you were watching a performance of the Shadow in an old-time theater, they might cast red lighting to indicate a Battlefield scene.
I like how it really serves to cut off the Battlefield and draw attention to it as being completely separate and the fact that I don't notice the light source at all. Sure I lose the color of the art there, but the design is still visible and the orange inserts are still a bit of a contrast. I had a plain warm white light in the spot light but it just looked too plain--there wasn't much as far as interesting art to be featured up there. Not pictured is the Kenner Thunder cab topper.
