Designed specifically for subcompact handguns, the Streamlight® TLR-7X 69424 Gun Light with Rear Switch features a snag-free profile for smooth holstering. The single, high-efficiency LED bulb delivers an impressive 500-lumen maximum output, illuminating targets out to 140 meters, while the durable, precision-machined, anodized aircraft aluminum housing easily shrugs off punishing recoil. Ambidextrous, customizable high/low rear switch controls readily accommodate right- and left-handed shooters, and a user-activated strobe function allows you to stun and confuse would-be assailants for reliable, non-lethal defense. The rail grip clamp system quickly and securely attaches/detaches to your pistol's accessory rail without requiring any special tools or putting your hands in front of the muzzle. Operating on a proprietary SL-B9™ protected Lithium-Ion USB-C rechargeable battery pack (sold separately) or CR-123A, the Streamlight TLR-7X boasts a 1-hour battery life on a full charge. Plus, a "Safe Off" feature prevents accidental activation during carry, storage, or holstering. IPX7 waterproof.
