The Streamlight TLR RM 1 is a 500-lumen rifle light built for shooters who need versatile, reliable illumination on the move. What sets it apart is the dual-switch setup: you get both a push-button on the light itself and a remote pressure switch, so you can choose your activation method based on your grip, position, and tactical situation. It comes packaged as a complete kit with everything needed to mount to any MIL-Standard 1913 rail—no hunting for compatible hardware or switches.
Runtime matters when you're training or hunting in low light. The TLR RM 1 delivers 1.5 hours of continuous output on a single CR123A lithium battery (included), with a strobe mode that extends to 3 hours. The engineered optic throws a concentrated beam out to 140 meters while maintaining useful peripheral light around your target zone. That balance between throw and spill is what separates a dedicated rifle light from a generic flashlight duct-taped to your rail.
The remote switch itself exits perpendicular to the rail, a thoughtful design choice that keeps your rail real estate open for other gear—optics, canting systems, whatever you run. A safe-off feature prevents dead-battery surprises or unintended activation in the pack, and the light is rated IPX7 waterproof, so rain and creek crossings won't kill your mission. At just under 3 inches and 2.74 ounces, it adds minimal bulk to your setup.

Yes. It mounts to any rifle, carbine, or shotgun fitted with a MIL-Standard 1913 Picatinny rail. The kit includes all hardware needed for installation.
The push-button is built directly into the light body, while the remote pressure switch attaches separately and routes at 90° from the rail, leaving your rail space open for optics or other accessories. You can use either or both, depending on your shooting position and preference.
On constant output, one CR123A lithium battery runs for 1.5 hours. Strobe mode extends runtime to 3 hours. The light comes with a battery included.
It's rated IPX7 waterproof, meaning it can be submerged to 1 meter for up to 30 minutes. That covers rain, wet brush, and creek crossings, though it's not designed for prolonged deep-water submersion.
