Surefire HL1-D-TN Helmet Led Light

This compact, multiple-output Helmet Light features three yellow-green LEDs, two infrared LEDs, and one blinking infrared LED that serves as a personal Identify Friend or Foe (IFF) beacon. The yellow-green primary LEDs are perfect for general-purpose, close-work illumination; the infrared secondary LEDs are for use with night vision devices (NVDs) and provide an invisible light signature when viewed by the naked eye.

Helmet Light features a durable, watertight polymer body in Desert Tan. Attaches to any Modular Integrated Communications Helmet (MICH) 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, Helmet Light can be quickly and easily slid on and locked securely in place. Pressing a lever on the mount unlocks the light, allowing for quick removal for servicing or transfer onto its optional Z71 carry clip, which attaches to any MOLLE or ALICE vest.
