Widen Your World | Haunted Mansion Traveling Light Effect (Brief) 1992 @widenyourworld | Uploaded August 2012 | Updated October 2024, 2 hours ago.
After looking around for a while this is apparently the only footage I have of the old traveling light effect, and it's only one window. The light passed through five windows when it was working properly, including the conservatory ... simulating something moving through the rooms.
