Chemlights, a type of light source, are items that once activated or equipped, will give off different-coloured light.
Chemlight[]
It has the same radius as an Omni Light, acts like an Omni light but are a shaded color (red, blue, and green), and are about as bright as an Old Flashlight. They are easy to be found and they spawn inside common buildings. These are also fairly common near the factory and in the abandon mine. They are great for looting towns at night, but the chemlight's brightness may attract bandits.
