We have to open a lot of door in our daily life.However,directions of opening them are different,that's why a symbolic design is made on each door .In this way ,it's very easy for people to distinguish the opening direction.During the daytime ,with high visibility inserting the key will not turn the indicator light on,while during the night,with poor visibility,it will turn the indicator light on.
