F101 Stealth Helmet Light Green / White / IR
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.
