If you’re referring to the blue light between the flippers, there’s a dipswitch setting that allows an orb to be deployed (when all four in/out lanes are lit) only ONCE per ball. After you’ve lit the four lanes without draining, and a single orb is deployed, the orb special light goes off. Otherwise, depending on the dip switch settings, that light will stay on, allowing an orb to be released every time you light all four lanes without draining. Hope that makes sense.
