This Spark Plug FlashLight Is one of those great inexpensive little gagets you just should'nt be without. It is a Single ultra bright white LED with a Spring Clip Keychain attached. It also has a Neat suprise, a miniature screw driver hidden in the removeable insulator cap. Just unscrew it and remove the screwdriver, just right for glasses, watches and battery comparments on radios meters and small electronic devices. These flashlights offer 400 percent more lighting range than a penlight, and reflector optics that enhance the brightness of the LED. Makes a great Gift.
