9-Volt Flashlight: a Simple, Bright Idea
This tiny flashlight is about as minimal as it gets. Just snap the little LED light unit onto the top of any 9-volt battery, and voilà, you have a fully functional source of illumination.
The compact light includes a trio of super-bright LEDs, which should be plenty for helping you find your keys in the dark. Thankfully, there’s a power switch on top, so you can leave it attached to the battery when not in use. While the design is clearly derivative of Richard Lawson’s 9-volt lights, I find these ones a bit more practical, while Lawson’s are definitely more stylish.
Kikkerland expects to start shipping these 9-Volt flashlights this October, and they should retail for under 10 bucks each.
