I've brought this up on a couple of other threads, so forgive me if you've seen it (I'm not selling these things I promise)- but this would be perfect for your ammo can "starter Kit".
(I just cut and pasted this from my other post.)

Solar, dynamo, rechargeable waterproof flashlights. I've purchased several of these over the past decade and give them out to family and friends as a way to plant a seed of preparedness (especially in my kids, I often ask them if they have their flashlight with them and they most often do). I also try to keep one of these in every bag, drawer, vehicle, outbuilding, and gun case. Of the 2 dozen or so I've purchased without regard to brand name, I've never had one fail yet, and the oldest in my stock still holds a good charge, stays charged if left in a sunny spot, and is able to be charged up with a quick crank. They are submersible for at least a short time, and needless to say I find them about the best thing since sliced bread.
I've experimented with other similar flashlights and greatly prefer the ones that look like this one, but have seen them sold under several brand names and colors.
I usually paint them with an earth tone texture paint that dries to create a bed-liner type protective coating that further waterproofs them, and I attach QD molle clips using a braided paracord thong making them even more handy. I have one of these hanging on every backpack and hunting pack, and they always seem to be charged up when I need them.
