The Streamlight Sidewinder Compact II Military Model Flashlight with Helmet Mount was engineered with an ultra-compact, high performance, multi-source LED flashlight that can operate on a single CR123A battery (included), or a single AA sized Lithium/alkaline battery. The four individual light sources, Infrared, Red, Blue, and White in color, selected with the pull-to-turn rotary knob, and can 4 intensity levels can be chosen with the on/off switch, from low to high output.

The included helmet mount will fit any Sidewinder series flashlight, and has a patented compound action design to allow one handed installation, removal, and operation of light on mount without the risk of accidental release. It is fully adjustable, with 360 degree rotation divided into 16 different locations, and the push button actuator allows fast attachment to the NVG bracket on HGU-84 helmets or the fixed NVG shroud most DoD, NATO, and ISAF combat helmets.
