Weird looking flood light on soldier helmet, what is it?

Hello everyone, I was looking at this video with a cool rotor glow effect but I have never seen the headlamps the army are using, what are those???

Are those glow tubes?


not a light but glow-sticks

Maybe its a camera effect but they seem pretty bright and the tint looks warm, I wonder who makes them?

As those solders all wear Nightvision I guess they are IR glowsticks or light to avoid friendly fire. but are not visible for normal enemies

I was just wondering why they would want lights on their heads.

To avoid friendly fire.
