Your flashlight should be waterproof.
Any good suggestions? I think My local Gander Has some pelicans I was looken at.
Pelicans aren't bad at all. I carry a 4Sevens Quark 123, which is waterproof and offers very high performance for the form factor. You could spend much less money and get a ThruNite Ti to have a 1xAAA flashlight that performs exceptionally well at an excellent price.
I've no affiliation with the manufacturers mentioned other than owning (what my wife would characterize as) too many flashlights.
