Are you afraid of the dark? Do you ever get a tad paranoid about being stuck in a blackout? If this describes you to a ‘T’, chances are you have a flashlight app installed, light keychain, and a spare in your bag. Of course, you can never have too many at your disposal as you just don’t know what life is going to present you.
Even if you’re not looking for a backup light for your backup light, the Eon Classic Credit Card Flashlight will hardly take up any space and will be easily accessible. This only weighs 1.4 ounces, and can fit in your wallet with the rest of your cards. It’s damage resistant, stainless steel, and its battery will run for 5-10 years. While this is rather convenient and won’t be lost unless you lose your entire wallet, it costs $14, so you may have better luck with buying something a little cheaper.
