While we're waiting for that great idea to come to market: My gear has waterproof BIC lighters in it. Go to a bike shop and ask for used inner tubes - offer to cut them so they know you're not mooching some freebies. Select a tube that is a close (but not tight) fit over the BIC - usually a road bike tube. Cut a section that is 3 x the length of the BIC, then cut 2 ranger bands from the same tube. Put BIC in the center of the piece of inner tube, fold the ends over, and secure with the ranger bands. It survives dry in the notorious swimming pool pocket test...

The tube serves as expedient fire starter, being easily ignited by the BIC - one can slice off some tube several times without hurting the seal. I also stuff 3-4 petro jelly cotton wool balls into the tube at the butt end of the lighter; sparklight tinder would be peachy if one prefers that.

It's deep black and doesn't glow in the dark, but this has worked exceptionally well for me.

No pics right now, but I can post some tonight if anyone wants.
