I came across a picture of these customized LED AE 125's that looked really neat especially with seeing all the different colored LED's being used here . These came up about a year and a half ago. There are a staggering 36 of them!
I originally thought the first time I saw it I thought it was all HPS and a crew came along and put them as a prank, turned out to be legit artwork where they swapped out the HPS for LED. Probably the coolest streetlight art I have ever seen. If anyone wants to see a streetview of them, Here it is
Think how awesome (and bright) it would be if they had used colored metal-halide's
