Designed to fit most pistols with tactical rails and featuring an easy-to-operate ambidextrous toggle switch, the Nightstick TWM-850XLS Weapon Light will help you identify a threat at significant distances and temporarily impair an adversary's vision. Simply press the switch down from either side for momentary activation, or click it up for constant-on. The light delivers 850 lumens, with a deep parabolic reflector for a long throw and a strobe for disorienting an attacker.

The TWM-850XLS comes configured to fit most pistols' accessory rails. It includes inserts specifically designed to fit Glock, Picatinny, TSW/99, and 90two rails. The housing is made of 6061-T6 aluminum that is impact resistant to 6.6', IPX7-rated water resistant, and submersible down to 3.3'. The battery door and toggle switch are made of glass-filled nylon. Power is supplied by two included CR123 batteries.
