Ah, they have been hung over the side of the building.
These box things were slid into the frames and some electrical wires were run. This last one was a tight fit so some high tech equipment was needed. A block of wood was placed on top of the stubborn last letter and it was then given a good whacking with a hammer until it was driven into submission.
While we have not seen it illuminated, this is the new signage.
That was a post saved for a rainy day, but then more happened. All the letters were pulled out and I guess electricians got to work.
It is rather ridiculous to have these repetitive labels.
And the Lord said there will be light, and there was. The sign now lights up at night but at some point go off during the night. They are not on at 4am but are by 5:30am until dawn. I wonder if there is an issue that the lighting shines into the highrise building, a road and a building along.
