SureFire HL1-A Variable-Output Helmet Light

New without box The SureFire HL1-A is a compact Helmet Light that features three white LEDs, two blue secondary LEDs and one blinking infrared LED that serves as a personal Identity Friend or Foe (IFF) beacon. Each colored LED comes in handy for different reasons. The white primary LEDs are perfect for general-purpose and close-work illumination. The blue secondary LEDs serve the same purpose but in more of a low-signature, night-vision-friendly color. SureFire Helmet Lights originally were designed for military and SWAT applications, but are also an option for climbing, carving, construction or search and rescue operations. The SureFire HL1-A is perfect for night navigation and close-quarter work like reading maps, loading gear or repairing equipment in the field. It is equipped with two toggle switches and a pressure switch for total control. A single CR123A battery keeps your Helmet Light running for a very long-time.
