Go Head To Head With Darkness. The compact, variable-output HL1 HelmetLight features primary and secondary LEDs and one infrared Identify Friend or Foe (IFF) beacon. The primary LEDs are perfect for general-purpose close-work illumination. The colored secondary LEDs serve the same purpose but in a low-signature, dark-adapted-vision-friendly color. Its durable, watertight polymer body attaches to any Modular Integrated Communications Helmet (MICH) via an included ambidextrous mount with 20 preset positions for true 360-degree rotation. With the mount in place, the HelmetLight can be quickly and securely attached. Pressing a lever on the mount unlocks the light for quick removal. An optional Z71 carry clip mounts the light to any MOLLE or ALICE vest. The HL1 is a highly versatile illumination tool for military, law enforcement, and tactical use.White and night-vision-friendly colored LEDs for close-quarter activitiesBlinking infrared LED serves as IFF beacon (all models)Infrared LEDs (some models) for use with night vision devicesTwo toggle switches and a pressure switch for total controlConstructed of durable glass-filled nylon polymer and neopreneEasily removable for servicing or transfer to other helmets (Z71 mount required)O-ring sealed, watertight body for dependable all-weather serviceLong runtime from a single 123A battery with 10-year shelf life
