Quick Take: Yes, the Hummer in Hummer Shake Flashlight refers to the same manufacturer that makes the oversize luxury sport-utility vehicles. But as you'll recall, Hummer's original vehicles were made for the U.S. Army and boasted rugged durability and utility in the harshest of conditions. The $30 Hummer Shake flashlight takes its design and usability from these more traditional roots. Marketed at the true outdoorsman, this flashlight sports a rubber-guarded design that's both shockproof and waterproof--it floats, too. Best of all, this hardy gadget doesn't require a single battery; instead, it generates power when it's shaken. Hummer also asserts that the flashlight's LED bulb never needs replacing, making this the ultimate lighting device for the great outdoors or just about anywhere else.
