The Fright Light. Look, I know it sounds silly, but I can see warehouse nighwatchmen walking around with one of these. Really I can. Kids? Pah! £8.99/$15.68.
The funky, chunky torch works as well as any, but the eight buttons on either side of the handle release anything from the crash of a thunderstorm to a chilling, evil laugh. As the sound plays the torch-light flickers eerily, enhancing the spooky effect. There are even three coloured filters to fit over the beam and enhance the effect.
