Fenix Flashlight CL05 LipLight Keyring Flashlight (Purple)

Reading in a tent, finding a keyhole in a dark doorway, staying visible while biking or hiking, signalling for help in an emergency—the purple CL05 LipLight Keyring Flashlight from Fenix does it all while hanging unobtrusively from your keyring. The LipLight emits white light for tasks and red and green light for visibility and signalling, in steady-on and flashing modes. Its circuitry makes such efficient use of a single AAA battery that the green light can flash as long as 21 hours and the red as long as 22. Turn the light on by simply twisting its base counterclockwise; turn it back off and repeat to cycle through the settings. It's also waterproof, able to withstand submersion to 6 feet deep for 30 minutes. The light measures just 2.9 x 0.7", weighs a half-ounce, and comes with a keyring clip.
