Our NightWalker isn't just a flashlight, but a clever Tri-Light that prevents the dangerous stumbles and falls all too common with ordinary, single-beam flashlights. In addition to seeing what's 10, 20, or 30 feet ahead, NightWalker's second beam reveals what's at your feet! So you won't trip over a box in the basement when you go down to check the circuit breakers in a power failure. Powerfully bright, highoutput Luxeon LED in front never needs replacing. Second beam uses two downward-firing LEDs to show you where to step. And a third, switchable red-flashing taillight makes you highly visible to traffic approaching from behind! Produces thirteen hours of brightness on three AA's (included). Gasket-sealed for use in inclement weather.
