Searching around in the dark can be scary. You never know what's going to jump out at you, and when the vampire werewolves finally show themselves, what are you going to do — hit them with your flashlight? If you're flashlight's a Stun Gun Mini Flashlight, that's probably not a bad idea, since it'll zap any would-be assailants with 200,000 volts. More portable than a tank and less obvious than a PHaSR rifle, the 6-inch-long SGMF comes with its own charger, which juices up the built-in nickel-cadmium batteries to full shock value in about 4 hours. An extra bulb is included — good to have, since one would think you'd probably use the flashlight's illumination abilities more than its death-dealing ones. All depends on your lifestyle, of course. — Peter Pachal
