The Sidewinder Stalk military helmet lighting system is designed to put light exactly where you need it with multiple mounting options and a flexible stalk to direct the beam. Equipped with White, Red, Blue, Green, and IR LEDs, along with an IR/IFF beacon, it offers versatile lighting solutions for various tasks. Each LED features low, medium, high, and strobe modes, and the separate Identification Friend or Foe (IFF) switch allows you to operate both the main light and IFF as needed. The white LED provides 76 Lumens on high with a 5.6 Hour runtime using a CR123A battery or 57 Lumens with a 6 Hour runtime on AA batteries. The Sidewinder Stalk can be mounted on any combat, vehicle crew, or aviation helmet system, MOLLE vest platform, or attached directly to the brim of a patrol cap. It features a push-button power switch and a pull-to-turn rotary selector knob, preventing accidental mode changes and enabling easy LED color selection. Rated IP67 for dust-tight and waterproof performance to 1 Meter, it meets MIL-STD-810H, Method 512.6 for durability. The high-impact nylon construction, gasket sealing, and corrosion-proof design ensure exceptional weather resistance and reliability in tough environments.
