The water clock was really cool. The colored water moves through the mechanism as the day passes. The bulbs fill up to display the time. The center pillar is a pendulum, I took the picture at the center of its swing. The time on the clock is 7:20 if that helps you read it. I took the other two pictures from the top of the Arc de Triomphe.
Here’s a streetlight near the Eiffel Tower.
