Nitecore's T2s Key-Chain LED Flashlight is a lightweight and compact light built to give you power and reliability without taking up much room. The low-output 2-lumen is suitable for checking under a seat or in a bag. To take out the trash or locate the fuse box, use the 20-lumen medium-output. The light provides 50 lumens at the top to illuminate the backyard or a dark lane. Finally, there is a warning signal that flashes to attract the attention of a tow-truck driver between the high and low outputs. It is switched on by a simple twist of the head, and cycles through the available outputs.
