The psychological anxiety and fear of passengers due to a momentary power outage greatly increases the incidence of safety accidents.
It is a lighting system that reduces the incidence of safety accidents and responds to safety accidents by providing psychological stability to passengers by turning on the emergency lights and the emergency call button at the same time to relieve the passengers’ psychological anxiety and fear.

In case of power failure, the inside of the CAR is visible through the emergency lighting system, but the emergency call button is difficult to visualize because it is dark.
Therefore, by applying the emergency call button lighting system, the emergency call button is visualized so that passengers can accurately find the emergency call button, so that safety accidents can be dealt with quickly.
