The Streamlight TLR-6 HL tactical light for Glock 42/43 is a compact, rechargeable weapon-mounted light built for concealed-carry pistols and home-defense scenarios where size and weight matter. At just 1.12 ounces and 2.5 inches long, it adds minimal bulk to slim, single-stack frames while delivering 300 lumens of bright illumination and an integrated aiming laser in a form factor that works where full-size light rails won't. Whether you're working a home-defense pistol, backup carry gun, or deep-concealment setup, the TLR-6 HL gives you the light and targeting capability of larger systems in a package that doesn't compromise your carry ergonomics.

What sets this light apart is the rechargeable battery system and the included charge case—no need to swap out single-use batteries or keep your gun tethered to a charger. Three batteries come in the box, providing about an hour of combined use, and the proprietary Streamlight SL-B2 battery can be swapped out even with the light mounted on your gun. The laser maintains zero after battery changes, so you stay sighted in. Ambidextrous push-button switches on both sides mean you can operate the light from either hand, and the durable polymer housing is tested to survive a 1-meter drop.

The TLR-6 HL comes in LED-only or LED-with-laser configurations—choose the model that fits your carry philosophy. Runtime varies by mode: roughly 20 minutes on light and laser together, or extended runtimes on laser-only modes. The beam throws 130 meters, and precise windage and elevation adjustments let you dial in the laser zero to your point of aim. If you run a Glock 42 or 43, this light closes the gap between micro-pistol practicality and tactical capability.
