SALW Moisture Sensor

Small Arms and Light Weaponry Moisture Sensors are light-emitting diodes that are integrated onto infantry weapons, most commonly pistols and rifles. They were developed for the Armed Forces - namely SEALs - for the purpose of making weapons easier to locate in the event that they are dropped into deep or murky water. Moisture Sensor lights are high-intensity and are typically blue, although the colors can be modified. It is estimated that nearly 84% of all small arms manufactured in the Verge after 2001 are equipped with Moisture Sensors.
