The Mitylite™ is made of unbreakable space age polycarbonate resin and is 4-3/4" (11.3 cm) in length. Its laser spot Xenon® lamp module can cut through water, smoke, fog, and rain making it a perfect light source for all applications. The MityLite™ is compact, light weight and equipped with a shirt clip, making it easy to fit into pockets, purses, tool kits, camera bags, or glove compartments. Accidental turn on and mechanical switch failure is eliminated because of the rotary on/off switch. You break it, we replace it... forever.
