When I worked there, we called those lights "work lights" because they were turned on only when someone entered scenes of the ride or behind them or above them, to do some kind of repair work. Usually, the work lights are on in the early morning prior to park opening so the work crews can fix things up for the day. The lights are turned off when guests come through so they can have that interesting "dark ride" effect. In my opinion, the ride was presented better to guests when the lights were off...but to the hard core fan who just wants something a bit different going through with lights on would offer that. I have heard folks say here they have gone through FITH with the work lights on and enjoyed it...but it too is meant to be a dark ride, and for the first time through, I hope everyone can enjoy it the way it was meant to be presented. I doubt if the powers that be would do it, but it might be interesting to have an organized SDC fans tour of all the rides someday with work lights on, and someone either a ride op or maintenance guy, leading us through to point out things of interest.
