Fenix ALG-04 Headlamp Helmet Mount

The tilt adjustment is the killer feature here—I can dial in the beam angle without loosening anything, and it locks tight enough that it stays put even when I’m scrambling up rocks. Being able to snap the light on and off the NVG mount in seconds has made it my go-to for night hikes.

Snapped it onto my FAST helmet in seconds and the light hasn’t budged during a full night hike. The quick detach is smooth enough to swap between helmets without any fumbling, and the angle stays put when I need it. Exactly what I wanted for a hard-use setup.

The angle adjustment is exactly what I needed—I can tilt the light down on the trail without the whole mount shifting on my helmet. It snaps on and off the NVG shroud in seconds, and the plastic feels sturdy enough for rough use.
