Just an Idea. A foot pedal that can work during special modes, or video modes to "catch" ghosts..
And when you press it the bottom of the cab uses a cheap small cheap LED projector and wide diffusion lens and LED Projectors/Flashers to put on a quick Ghost Trap Open and Close light-show.
Crappy PS mockups included.
I also put the bolt on replacement pluger to GB wand swap.
