Where there is the possibility of the presence of chemicals, flammable gases or flammable liquids. They are available in various colors. They have a body length of 10 to 40 centimeters and a glow time of 5 minutes to 12 hours. Due to their size, HIS can be of little use for the assembly of small-sized wearable survival kits.

A chemical light source consists of two components, one of which is an activator, and the other is a luminous composition. Both substances are enclosed in a sealed plastic case. One reagent is placed in a glass capsule. To activate a chemical light source, it is necessary to bend and crush the glass capsule. Then shake. Reagent substances mix and produce light, the brightness of which depends on their composition.

It should be remembered that at low temperatures, the intensity of the luminescence of CID decreases, and the operating time increases. At high temperatures, the opposite is true. Chemical light sources have a certain shelf life. It is indicated on its case or on the packaging, usually up to 4-5 years. As an alternative to a chemical light source, if necessary, 360 degree circular lighting, white, red or orange nozzles for AA or AAA format lights can be considered.
