Why can't the hotel room lights be turned off completely?

The reason why this happens is for security reasons.

For safety reasons, all the lights in the hotel room can't be turned off. Sometimes there are guests who have been drinking, and there are also guests who have taken their children to the hotel. Leave a small lamp with a soft light on, which is convenient for guests to get up at night, go to the toilet, drink tea and find things. If all the lights are turned off, it will be dark and invisible, and it is easy for guests to fall or knock over things after getting up, so for safety reasons, the lights in the room can't be turned off.
