The Streamlight TLR-8 HL-X Sub Handgun Weapon Light for SIG P365/XL closed rail systems is a high-lumen rail-mounted tactical light that delivers 1000 lumens for extended visibility in low-light conditions, helping shooters acquire targets with confidence. This versatile system accepts either the Streamlight SL-B9 USB-C rechargeable lithium-ion battery or a single CR123A battery, allowing you to choose the power option that fits your mission or range routine. Ambidextrous rear paddle switches provide both high and low settings to accommodate different shooting styles while keeping control intuitive. Built around durable anodized machined aluminum, the TLR-8 HL-X Sub is engineered to withstand demanding use, and its IPX4 water-resistant rating ensures reliable performance in challenging environments. An integrated red laser gun light adds targeting precision, with a runtime of up to 29 hours, and a user-enabled strobe function adds versatility for signaling or disorienting potential threats. Designed specifically for subcompact pistols like the SIG SAUER P365 and P365 XL, it mounts without obstructing your grip, making this Streamlight accessory an essential choice for personal defense or law enforcement applications, backed by a limited lifetime warranty.
