Reflections:
First of all, assuming the person who would find these useful doesn't have in-house lights they can turn on in the middle of the night, how are they going to find these slippers anyhow? Perhaps they should come with a remote homing device that attaches to your PJs (because the person who would purchase "brightfeet" have been burned by candlelight too often, live in a cave, have no electricity, have other house residents who awake suddenly when someone turns on a hall light). If, by chance, they are useful to you, I doubt you'd find them functional. How in the hell are you going to see anything with lame key chain-esque lights strobing from your toes? Avoid the family dog or a ball of lint I suppose. I think headbands with lights on them would be better. At least they would illuminate what is at eye level.
