Surefire HL1-A Helmet Light in Black (HL1-A-BK) is compact, multiple-output Helmet Light that features three white LEDs, two blue secondary LEDs, and one blinking infrared LED that serves as a personal Identify Friend or Foe IFF beacon. The white primary LEDs are perfect for general-purpose, close-work illumination. Blue secondary LEDs serve the same purpose, but in a low-signature, night-vision-friendly color.

The Helmet Light features a durable, watertight polymer body available in Black or Desert Tan. Black models attach via an included low-profile mount that clamps semi-permanently to the rim of any Modular Integrated Communications Helmet MICH via two socket-head machine screws. Tan models attach to the same helmets via an included ambidextrous mount with 20 preset positions that allow the light to be rotated 360 degrees when attached. Once either mount has been attached to the helmet, the Helmet Light can be quickly and easily slid on and locked securely in place.
