These are great lightup pins what have a receiver in them so they react with their surroundings in disney. For example, the red lights will strobe like a heart beat at the end of the Haunted Mansion. In parades they will glitter. They are very cool and if memory serves me, they are about $15. Last year they were sold at the pin stations, all of the hotel stores, and most park stores. We're bringing ours back from last year with new batteries (they don't last long). One tip. I'm not sure if they changed the pin backs from last year, but they used to fall off ALL THE TIME. The pin stations sell rubber backs for like $1 for a bag. It's WELL worth the investment.
