Surefire KM1 3V Infrared/White Light M300V Series Bezel, Black - 250 Lumens/100mW

The Surefire KM1 3V infrared/white light bezel is a tactical upgrade for shooters and operators running M300V series Scout Lights who need dual-spectrum capability from a single compact unit. Swap your existing bezel for the KM1 to add 250 lumens of white light output plus 100mW of infrared illumination, giving you mission flexibility without replacing your entire light. Rotate the bezel to switch between IR and white-light modes on the fly—no filters to swap or fiddle with in the field.

Built from lightweight aerospace aluminum and hardened with a Mil-Spec hard-anodized finish, the KM1 is engineered to take punishment. The proprietary TIR lens delivers a high-intensity beam with useful surround light, balancing reach with situational awareness at medium to longer ranges. Both the infrared and white LEDs are designed to be virtually indestructible and regulated to squeeze maximum output and runtime from a single 123A battery.

If you're already invested in an M300V platform, the KM1 bezel swaps easily to modernize your setup. It's the kind of upgrade that makes sense for dedicated operators, precision rifle shooters, or anyone who's run a Scout Light and wanted the option to go dark when needed. No permanent changes, no new mounting hassles—just better capability when you need it.

Frequently Asked Questions

Will the KM1 bezel fit my existing M300V light?

Yes. The KM1 is designed as a direct bezel replacement for the M300V series Scout Light. It swaps in place of your current bezel without modifications.

Can I switch between infrared and white light without tools or filters?

Correct. Simply rotate the bezel to toggle between IR mode and white-light mode. No filters to remove or install, making it practical for rapid mode changes in the field.

What battery does it use?

The KM1 operates on a single 123A battery, the same power source used in the M300V platform.

What makes the TIR lens design valuable for medium to longer-range work?

Surefire's TIR lens creates a high-intensity central beam with useful surround light, giving you both reach and situational awareness at distance without losing the peripheral vision you need tactically.
