Quoted from ZMeny:The path from Pro to Promium continues...
Added ramp lighting, colored posts, and Pin Stadium lights
That's a drawback of Pinstadium - or any LED strips - installed on the side walls when the game has plastic ramp returns along the sides. You get the reflections from the LEDs on the plastic. I have moved around my Pinstadium kit from game to game and Mustang and Metallica have the same issue. Even though Met has wireforms, the plastics below really reflect the LEDs.
Not an issue on Baywatch or Big Hurt, my two games that really needed a light upgrade, since they do not have anything under the LEDs to reflect off of.
