Ghostbusters Proton Pack lights and sound prop replica. Light and Sound kit from Hyperdyne kits. I swapped out all the leds in the gun wand with really really bright ones. The pack includes a motor in the wand that spins when you push the trigger button. I also wired up the rechargeable battery to have a port in the back of the pack so I can charge it all the time.
