Forget the Mickey Mouse Ears my number one most favorite souvenir to buy when I visited Disneyland were the light up hats. In particular I liked that visor with the lights that would blink, especially the Captain EO one.

These were spotted in MouseGear inside EPCOT for those on the hunt for one of their own.
