Compact, lightweight, watertight, multiple-output unit that can be attached to military PASGT and TC 2000 Modular Integrated Communications (MICH) helmets, as well as caving, climbing, construction, and search-and-rescue helmets.

The Helmet Light uses a single 123A lithium battery, three separate switches, and six light-emitting diodes (LEDs) to produce three different types of light at multiple power levels:

- Primary light - three 5mm white-light LEDs with low, medium, and high output levels

- Tertiary IFF light - one 3mm, 880nm infrared LED with continual blinking output

White lights are for general-purpose close-work illumination.

Blue lights serve the same purpose, but in a low-signature, night-vision-friendly color.

Blinking infrared light serves as a personal Identify Friend or Foe (IFF) beacon.

Attaches to thick-rimmed helmets (including MICH helmets) via a close-fitting, low-profile mount that clamps to the left-side rim. Some helmets may require drilling two small holes. Helmet Light unit may be removed separately from mount.
