NEWER UPDATE: This arm was replaced with a tapered e arm and now LEDs are beginning to take over. 2 Unidor 250s were replaced and 2 R37s. All 4 were mercs. Interesting because this spot is border between 2 district regions. The one on the left is replacing everything will LED. The district to the right is still using HPS. Model 13`s and a few Unidors are still up and running. (for now)
