The Super PeliLite™ is made of unbreakable ABS material with a hi-impact polycarbonate lens. Its laser spot Xenon lamp module can cut through, smoke, fog, and rain, making it a perfect light source for all applications. Accidental turn on and mechanical switch failure is eliminated because of the rotary on/off switch. It requires 2-C cell Alkaline batteries (not included) and is submersible to 250 feet. You break it, we replace it... forever.
