So everyone knows, lights going out on a timer at 11:00pm is not normal. No it hasn't happened regularly in the past. It normally only happens when a president dies. There was an exception while Trump was in office during the DC riots they turned out the lights a few nights to deter the crowds. Just know, it's not normal no matter what the sheep tell you it is. Here's some timestamped photos after 11:00pm with lights on. Feel free to use and share.
Yes, I have been watching these lights go out every night at 11:00pm for about 2 weeks now. (honestly, I haven't counted the days that this has been occuring)
