This article describes a feature in the first Apocalypse Rising
Chemlights are a type of light source. Once equipped, they will give off a colored light.
Chemlights have the same light radius of an Omni Light and are equipped similarly. They give off a red, blue, or green light and eventually stop glowing. These are commonly found and can spawn in any civilian loot building. These are great for looting towns at night but the glow may attract bandits. Many people who use these are considered "noobs" or not well equipped people, but some bandits will equip these for the purpose of drawing "Pro" people to them. Chemlights do not attract zombies.
