People usually spend a lot of time waiting the elevator in the commercial building or department store which always crowded by people. It will take you more time especially when the elevator arrives to your floor but it’s full loaded. This design hence to use the light that can show different colors to indicate whether the elevator is full loaded or not. If the light is green, it means the space in the elevator is not full loaded yet. If it’s red, it means the space is full loaded. People who are waiting at other floors can choose to take the stairs to save energy and their time.
