I have a lanyard that has a bunch of glow in the dark pins on it, and the girls went from being scared of the dark to being really excited to get to the dark rides so they could see which pins glowed and which didn't.
Having been on the rides a bunch of times, I have yet to be annoyed by people with lights, so while I would say that theoretically it would annoy me, in practice it hasn't because I *know* other people out there must be using them and I haven't noticed it.
