A childhood belief about in the street

I remember being in the car when it was beginning to get dark and seeing the street lights turn on one by one. I thought that there was a massive room full of thousands of computers, one for each lamp and there was a man who had to switch them on individually. When I was about 7, we watched a 'Come Outside' video at school which explained that therre are sensors which can tell if iut is dark and switch them on. I couldn't wait to get out of school that day to tell my mum the 'truth'!
