One of the newest technologies to enter the flashlight and personal safety lighting industry is not new at all. Electromagnetic induction, an old technology is now being used in hand-held flashlights by consumers, security professionals and government agencies and this proves to be a trend which will continue for quite some time. With battery life issue with stored flashlights, often when one is on the side of the road with a flat tire and reaches for the flashlight in the cold and dead of night, it will not work. The batteries are dead and it is too cold for them to even get a faint glow out of the flashlights high-intensity glow. By using electromagnetic induction one can shake the flashlight and then use the energy created to light up the scene.
In harsh environments one has to worry about snow blindness and safety flashlight need additional lens covers or bulbs to be of any true value. Perhaps for those who must leave their cars on the side of the road and start to walk, then need not be run over in the snow or moonless night as a red light behind and a white in front, both LED could solve this problem as well.
For those who walk at night
