This Sidewinder Stalk Helmet Light is made entirely out of impact-resistant synthetic material. It can easily be mounted onto the ARC accessory rail on a tactical helmet. The lamp can be bended slightly so you can shine a light right where you need it. You can choose between a number of different colours, such as red, green, blue and more, as well as a stroboscope function. Even the brightness can be adjusted. The Sidewinder Stalk Helmet Light Replica can be mounted onto the side of your helmet, which means simple operation is of utmost importance. It features an on/off-button and one selection wheel, which you can use to access all of the lamp’s functions quickly and efficiently. This lamp is powered by a CR123A battery.
