Electric water clock on Saturday

What would be the ruling if it were depicted that there was an incandescent bulb in a water clock that turned on when water passed or some other Torah prohibition?

Nowadays, there are lights in private homes that turn on when you pass by them, and I have not seen anyone being careful to avoid passing by such lights (it is possible that some of them are illuminated by an incandescent bulb).

Regarding the lights that are turned on by someone passing by, Rabbi Wesner has already written (in the response to Shevat Halevi) and further that this is permissible. However, this is because the person who placed the light did it for his own needs and I am just passing by and he cannot forbid me from passing in the street. For the answer, this is not even a deliberate act, but at most a distraction. I do not do both things but walk, and the light turns on by itself. But with us, he consciously activates both things (like dragging a bench and creating a groove) and furthermore, it was placed there for his own sake (as a condition for using water).
