Standard issue for U.S. military personnel around the globe, the ChemLight brand is the gold standard in chemical light technology. When the Navy has a man overboard, they reach for a ChemLight to mark his location. When a downed Air Force pilot needs to mark his position for extraction, it’s ChemLight he trusts. These infrared SOS signal devices allow individuals to easily mark locations without the need for visible spectrum lights.

There are 50 SOS signal markers per case. Each is packaged in a hard plastic case that doubles as a handle for protection from light and moisture, boasting a four-year shelf life from date of manufacture. This product is non-toxic, waterproof and non-flammable. ChemLight meets Defense Logistics Agency (DLA) and NATO Maintenance and Supply Agency (NAMSA) specifications. As such, National/NATO Stock Numbers (NSN) are printed on each product for reference.
