I found this cool flashlight at Target for $5.19 and couldn’t pass it up. This guy on YouTube gives a pretty good demo: YouTube - Life Gear Glow Sticks I got the blue one, but red, green, and orange is also available, according to Life Gear’s website http://www.lifegearcompany.com/glowsticks.html The cool thing about it is the glowstick part. Sure, it’s a flashlight, but hit the switch again and the whole body of the flashlight lights up. Hit the switch again and the flashlight goes out but the glowstick part stays on. Hit it once more and the glowstick flashes. The glowstick part puts out enough light to read by at night. And there are no chemicals in this, like a Cyalume, so it doesn’t die after a few hours. They claim it will last 200 hours on flasher mode. The flashlight is 7.5 inches long and about .75 inch in diameter. It comes with a 20 inch lanyard with a quick-detach coupling. As shown in the video, you can swing the light by the lanyard in a circle and it will make a much bigger and brighter signal than just waving the thing in your hand. You can also pull the cap off of the end and there is a built-in whistle. Someone put a lot of thought into this and came up with a great little tool. It’s cheap enough to buy several and put in your glove compartment, boat, backpack, survival kit, etc.
