Always have a handy light, and help a worthy cause, with the pink Nano Light from Streamlight. For each one purchased, Streamlight will donate $1 to the Breast Cancer Research Foundation. A double-sided FOB features the Breast Cancer Pink Ribbon on one side and the Streamlight logo on the other side. With a modest 10 lumen output it is well-suited to finding key holes in the dark, reading maps, and other similar tasks, and its rotating on-off head switch makes it easy to operate with one hand. The aluminum alloy body is protected by a scratch-resistant pink anodized finish, and simple snap-clip allows for one handed attachment and removal from key rings or straps. At a mere 0.4-ounces, including the four LR41 batteries, the Nano Light won't weigh down your keyring.
