I love the Mini Amber 9V flashlight! Soo handy! When the battery dies (after a long time), they can be used with rechargeable batteries. I invented a great hack for them: Taping a small square of white silnylon around the top with regular packing tape turns it into a tiny lantern. It still works as a flashlight. But the silnylon looks like a big flame and lights up the room with great ambient lighting. Silnylon weighs nothing and folds over the flashlight in my bag taking no space at all, yet makes a big difference. I keep one of these on my bed-side table. And I bring lots on vacation. It is as useful camping as in a rented house. When the place does not look good, this amber light makes everything more beautiful - including me! ;-)
