https://en.wikipedia.org/wiki/Elevator
In addition to lanterns, many elevators in North America have a chime to indicate if the elevator is going up or down either before or after the doors open, usually in conjunction with the lanterns lighting up. Universally, one chime is for up, two is for down. These chimes are required in Canadian jurisdictions that have adopted the NBCC.
