Olight i3E EOS Mini Flashlight

This is a very small (2 3/8 ' long), very lightweight metal flashlight that you can put just about anywhere. I have one and I put it on my survival lanyard along with a mirror, whistle, ferro rod and striker and a waterproof match case and it fits in great with those items. It uses one AAA battery which is also included with this flashlight. This is another great choice when you want a lightweight flashlight that takes up very little space.
