Streamlight Sidewinder Stalk with Helmet Clip Black Mailer Your helmet is heavy enough without adding a bunch of extra gear to it. The Sidewinder Stalk lighting system was designed to cut down on the number illuminators an operator might need to carry. The LED head has white, red, blue, green and infrared options for use with night vision, all on a flexible stalk so you can put the light where it is needed. There is also a separate IR/FF, friend or foe ID strobe that operates independently of the LED lights. This small light is packed with capability and versatility. Manufactured from a high-strength polymer and an unbreakable polycarbonate lens, the Sidewinder Stalk meets MIL-STD-810H standards and has an IP67 dust intrusion and water resistance rating. When you need a helmet mounted light that does more with less, you need a Sidewinder Stalk from Streamlight.
