ya those spotlights on Metallica sling shot plastic are ridiculous. I removed mine, can't really notice any difference. My apron is metal and powder coated candy purple and has interactive lights put in by Pinball Refinery. The lights are 2 square things installed under where you grab to lift the playfield. I believe this bar will clear these lights where they are attached. What about when we have to lift the playfield up? Is these light bars have the room, or its gonna be tricky to do? I will be interested, but I may need purple so it matches the apron. I will be following your progress on this. I will be in on one for sure if it not gonna interefer with the LED's currently there.
