We stayed over at WDW for my birthday this weekend and rode the PeopleMover both Sunday and Monday. On Sunday, we noticed these weird work lights were all lit up inside Space Mountain making it very bright in there. The following day, not only were those lights on, but Space Mountain itself was down and all the Space Mountain lights were on too making the track entirely visible.
Here’s what the ride-through looks like currently with the lights on but Space Mountain running:
