I got tired of the ring insert basically being a washed out mess so I made this mod:

It appears Stern painted the top of the Ring LED board flat black to try and stop light bleed, it is not overly effective. They were also hit and miss mounting this board so the LED's may not align with the inserts. This "puck" stops the light bleed and tones down the Elf rings (white ones) as they are super bright. The puck also includes parts that will allow you to adjust the board to better align with the inserts. For the video the lights in the room and camera settings were not changed so this is a pretty accurate view of the difference:

Terry is selling them at Pinball Life:

BTW, I had my 16 year old make the promotional video, he had total artistic control, so if you hate it, blame him
