Mixture of different street lights, old and new, along Dixon Street in Wolverhampton. Straight ahead is an old steel 8m column with a Thorn Alpha 9 (LPS/SOX), with a post-top Philips Digistreet (LED) and Urbis ZX2 (HPS/SON) on a 12 column in the background, and to the left you can just about see an Urbis ZX1 (HPS/SON) in the tree as well.
