Here's a short example video. The GI lights that can be seen best include those under the slingshots, under the outlane dividers, and in the upper right of the playfield.

This video starts with a machine with LEDs, but no GI OCD. It then shows the same machine with the same LEDs after installing the GI OCD kit.

The game in the middle has LED OCD and GI OCD installed. The other two do not. Thanks to a customer for this video.
