Before you get imaginations wild, it is about the light sensor system.
In toilets and many other places, lights are switched on/off using sensors. This does save a lot of power. Apparently the place where it is positioned matters. If for example the sensor is placed at on the wall. Higher it is placed the darker would be the toilet room when a person of shorter height enters till he/she covers a distance in the dark.
