I'm looking for personal lighting for Ephemerisle, ideally with the following properties:

a) powered by removable, rechargeable batteries (AA/AAA/18650)
b) durable
c) waterproof / resistant
d) inexpensive (under $20)
e) available through Amazon
f) non-distracting / slow transition between between lighting levels/colors (no strobes/blinkies)
g) long battery life
h) on/off switch (doesn't require removing battery to turn off)
i) small / lightweight
j) can be easily attached to clothing without damage

Most of the lighting solutions that are inexpensive use disposable CR2032 batteries, which I'd like to avoid.

Something like this, but with rechargeable batteries:
