The light can also help during an emergency. If there is a fire, power problem, or unexpected situation during the night, being able to see the room clearly may make it easier to locate the door and exit quickly.
A dim bathroom light may also prevent accidents when walking around at night. Suitcases, shoes, furniture, or other belongings left on the floor can become easy to trip over in complete darkness.
Some people also believe that leaving a light on may discourage an intruder by making the room appear occupied and awake. While it is not a guaranteed security measure, keeping a small light on can provide extra visibility, comfort, and convenience during a hotel stay.
