Near my house last week I saw these sitting on a traffic island at a major intersection:
The truck parked next to them was full of boxes with 'LED' written on them. Later I saw them putting them up:
They had to remove the (dust covered) old lights, which allowed for a comparison.
In a few hours all the lights on the main street had been changed, and I was greeted with this shiny bright walk signal.
One wonders how long it will take for them to become covered in dust and soot.
