Light Sources

It is important to have a light source at all times. The great need to have a light source at the ready and on the go is simply because the power grid may fail or a custom means of energy source may fail and conventional lighting may fail. Preservation of energy sources may be of utmost importance, however it may not be a potential reality during an emergency where having a light source can mean the difference between stumbling around in the dark and perhaps getting injured or safely navigating around dark areas until coventional lighting are operational.
