Streamlight TLR-6 Weapon Light for Glock 42/43 - 100 Lumens, White LED, 89m Beam, Matte Black

The Streamlight TLR-6 is a compact weapon light purpose-built for Glock 42 and Glock 43 pistols. If you carry a subcompact 9mm or .380 for concealed work, everyday defense, or backup duty, this light gives you the ability to illuminate a threat quickly without fumbling for a handheld. At 100 lumens with an 89-meter beam, it throws enough light to identify a target and overwhelm low-light vision—practical for home defense, vehicle stops, or any scenario where you need to see what you're shooting at. The TLR-6 mounts directly to the rail under your Glock 42/43 and stays there, so you're not adding a separate device to your draw or retention.

This is a weapon light engineered for concealed-carry guns, so size and weight matter. The TLR-6 is slim and lightweight—just 1.27 ounces with batteries—so it doesn't change the balance or profile of an already compact pistol. Ambidextrous push-button switches on both sides let you activate the light from either hand, a critical feature if you're operating in a tactical or self-defense situation. Press once for constant-on illumination, or press and hold for momentary—your choice based on the moment. The light runs for 1 hour total on two included CR1/3N lithium batteries, and there's a 10-minute auto shut-off to preserve battery life if you forget to switch it off. Even better: you can swap batteries while the light stays mounted on the gun, no re-zeroing required.

The TLR-6 is built to handle hard use. The housing is durable impact-resistant polymer, tested to 1-meter impact resistance, and the lens is glass with a shock-resistant seal. Streamlight rates the LED at 50,000 hours of operational life, so you're not replacing the light source anytime soon. The unit is serialized for positive ID and assembled in the USA. All of that backed by Streamlight's limited lifetime warranty.
