Review on Twilight Zone Pinball Spiral Sign by Ruben Saunders

I've always been annoyed by the bare bulb that illuminates the spiral area. This plastic definitely solves that problem. The main issue I had was the need for constant adjustment when the plastic or bulb slipped. This was solved by adding a layer of silicone sealant after the bulb was inserted into the socket. Since then I haven't had any issues with the plastic twisting or the bulb falling out due to the extra weight of the added plastic. Great idea, but maybe there's a better way to mount it.
