when did it happen?

that all the pedestrian lights were changed?
I never saw a single one being worked on. Like in a fairy tale, one day we woke up and it had happened.
According to Gothamist, since 2000, the Department of Transportation installed new LED lights at:
- 2,800 intersections in Queens and Staten Island
- 3,700 intersections in Brooklyn
- 1,500 intersections in the Bronx
- 2,700 intersections in Manhattan
