This emergency evacuation indicator light is usually installed in corridors, passages and other positions in buildings. Under normal power supply, it can be used as an ordinary identification light; when emergencies such as fires occur and power is interrupted, it can automatically switch to the emergency lighting mode. Through the eye-catching green background and white evacuation signs (such as running human figures, arrows, etc.), it can clearly guide people to quickly and accurately find the safety exit. It is an important fire-fighting equipment to ensure the safe evacuation of people in emergency situations.
