The Gadgeteer has covered a lot of flashlights in the past, but I don’t recall seeing a flat one before. This little Flat Flashlight from Perpetual Kid is small enough to fit on your keychain or in a pocket, so you’ll never find yourself without a flashlight again. It’s only 2.5 inches long X 1.75 inches wide, and it has a cool retro styling. It’s only $6.99, so you can have one on your keychain and a couple others stashed around without breaking the bank. It would also make a cool bedside flashlight for those monsters-in-the-closet emergencies kids sometimes experience.
