Combat Light Shield Cyalume with Light Sticks

Great idea to regulate direction of light, chem lights are single use with no 'off' switch, so useful if circumstances change e.g. you get rescued or you want to sleep or go dark. Advantage of chem lights is they can be used during gas leaks or near spilled fuel and underwater. So will still work in deluge weather next to a car wreck. These are simple, lightweight devices that are easy to use.
