Is it safe to install voice control lights in elevators?

It is not good to use voice control lights in the elevator room. The elevator room must be a ever-burning lamp. It is safer to take the elevator. There are often old people and children in the elevator. For safety reasons, it must always be open and ventilated. If you use voice control lights, it is too dark and scary, and it is more troublesome to control the voice control time badly, so the lights in our elevator room must be on all the time!
