Meprolight's MEPRO LIR is a personal marker designed specifically as an individual identification device for fratricide prevention. MEPRO LIR was designed in response to requests by special military and police units for an infrared identification device. The device is resistant to shock, water and most oil-based solutions. Since MEPRO LIR is placed on the back, or the rear of the helmet, it includes a digital control panel that is connected to the marking unit via a wire. The panel enables the user to see any malfunction, as well as information about the light intensity and illumination panel. MEPRO LIR is the only personal marker of this kind that includes a personal control panel.
The signal is emitted by high-power infrared light-emitting diodes (LED) at a wavelength that cannot be detected by uanaided human eye. When viewed through night vision systems, the IR light can be seen at long ranges.
MEPRO LIR, which complies with Mil-Spec requirements, is available in two models:
- SWAT Model – with a single IR element usually placed on the back, behind the shoulder.
- Military Model – two elements, one in front and the other on the rear of the helmet. The rear element is capable of working in a visible range, usually Yellow (other colors available).
