Maglite makes many variations of their famous flashlight. The five D-cell light is one of the best they make. It is sturdy and non-breakable. Not only is it a highly efficient light source, but it can also be used as an effective self-defense baton. The aluminum tube and rubber shrouded switch are waterproof making it an excellent choice for adverse weather conditions. There is an additional bulb stored in the base cap. Whenever I have a situation where I need to go out at night, I always carry a Maglite.
