This is a simple mod for the Stranger Things pinball machine by Stern (Pro/Premium/LE).
It replaces the flasher dome on the upper left side of the left ramp.
You also need a 0.5mm plastic plate to build the window of the chamber. I painted the inside of the window green and hot-glued it so it gives this strange look.
