For those that want to customize their game a bit, I just designed and made a few of these custom lamp covers. They are made from polished 18 gauge stainless steel and feature a unique design that mimics 1950's neon signs. The arrow runs along the top of the lamp cover to across the bottom of the text. Also, the back of the lamp features a surprise message from Rudy. I really like how this came out. I only have five left and not sure if I'll get a chance to make another set.
They can be ordered from my pinside shop: https://pinside.com/pinball/market/shops/1025-professor-pinball/01148-funhouse-custom-lamp-
