Limited Edition activate colors/sounds, but only at their 'home park.' So party bands only change colors at Magic, Star Wars at DHS, etc. Any that are sold in multiple/outside generally only activate at the enty points though some, like the Awaken Summer promotion bands' activate everywhere
The DVC one, the Alice Mad Hatter one, and the ones they sell at MNSSHP and the Holiday parties. Those are a few. And the Easter one on Shop Parks, and the Star Wars LE ones they sold on May 4 and May 5.
I wanted one, but read they only have the special sounds and colors at park entry? Not at the ride band scanners? And some only work at one of the parks.
