Streamlight TLR-3X USB 500-Lumen LED Weapon Light - SIG Sauer P365/XL

The Streamlight TLR-3X USB is a compact rail-mounted weapon light purpose-built for SIG Sauer P365 and SIG Sauer P365 XL subcompact pistols equipped with the factory closed rail system. This USB-rechargeable variant pushes 500 lumens of white LED output with a peak beam intensity of 6,500 candela, projecting a tightly focused beam out to 161 meters for confident threat identification at realistic engagement distances.

The TLR-3X USB runs on Streamlight's SL-B9 rechargeable battery pack, topped off through the integrated USB port so you never need to swap disposable cells. It delivers up to 1 hour of continuous runtime per charge. Housed in a rugged polymer body in matte black, the light measures just 2.75 inches long and weighs approximately 2.15 ounces, preserving the concealable footprint that makes the P365 platform so popular for everyday carry. The unit is waterproof to 1 meter for 30 minutes (IPX7 rated) to keep working through rain and incidental immersion.

Streamlight's rail-grabber clamp locks the TLR-3X USB securely to the P365 closed rail, and ambidextrous paddle switches provide instant momentary or constant-on activation for either-handed shooters. Whether you carry a P365 or P365 XL for personal protection, duty, or home defense, the TLR-3X USB adds serious illumination capability without sacrificing the slim profile that defines this SIG Sauer pistol line.
