Street lights have been going off since 1st of April so possibly it was reported by the other outlets at the time. Although I didn't see much about it prior to happening.
First I knew was getting up in the middle of the night to have a pee. Our bathroom is nicely illuminated by the street lights outside, but I went in there, and couldn't see a thing, in that half awake state, I thought I'd gone blind !
I don't recall any announcement about it. There's anecdotal evidence that crime in some areas has increased. It's certainly annoyed folk who walk back home from clubbing etc at the weekends.
