The Helmet Light HL1-B-TN from SureFire is a versatile hands-free light that provides visible white light or IR illumination with an IR Identify Friend or Foe (IFF) beacon for identification to friendly forces using NVDs. The light features three white LEDs offering up to 19.2 lumens for tasks, or two IR LEDs with a maximum output of 2.5 lumens that act as an IR illuminator for use with NVDs. The light output is controlled using two toggle switches. The first switch turns the IR IFF beacon on and off. A second switch controls the white or IR emitters and turns them off. A pressure switch on the face of the light controls the intensity of the light chosen. Pressing the button cycles through the low, medium and high levels. When attached to the helmet, the light can be rotated 360° with 20 click-stop positions to precisely put the light where it is needed. Built for durability, the light is o-ring and gasket sealed to be waterproof.
