The Opsmen F101 Stealth Survival Light is a multi-function IFF marker that can be mounted on a helmet or other surface with a velcro base.

Features
The light is waterproof and has two modes of operation with two functions under each mode. A 3-position function switch allows you to turn the light on and select one of the two functions available. A dedicated mode switch toggles between the visible and IR modes to maintain illumination discipline.
The function switch features a nub below to allow checking the selected function by finger-feel even with gloves on. The mode switch has a smaller similar nub above, or you can just memorize "Visible / Front" and "IR / Rear" - assuming you mounted the light correctly. The light provides vibrating feedback to confirm it has been turned on in the IR mode.
To eliminate potential leakage points, the switch sliders feature small magnets that control sensors on the inside of the solid body.

Only 2 slight downsides:
Buttons are VERY loud and hard to activate (i suppose that is unavoidable for waterproof switches) and the surface of the translucent plastic, even though matte, still is too reflective/shiny in my opinion.
