In an age of advanced technology, the simple chemical light stick, or chemlight, remains a staple. Its usage scenario is for marking, signaling, and providing low-level area lighting without giving away your position to the enemy like a white light would. They are waterproof, require no batteries, and are extremely lightweight and reliable.
They can be used to mark cleared rooms, pathways, landing zones, or casualties. Different colors can convey different messages. The efficacy is simple, dependable, and passive light that enhances safety and coordination without electronic signatures.
Choosing to carry a few chemlights is a matter of basic preparedness. They are a redundant, non-technical solution to a common problem. Their reliability and simplicity ensure they will remain in tactical kits for years to come.
