This might be a bit late but, for anyone else wondering, I figured out that the lamp post itself may be based on power lines. It would only rotate if there is a power line nearby, similar to the vanilla electric poles in the way they rotate themselves. Wish it was more explained or, that it can be rotated via R hotkey, but hope this helps. Just noticed that this mod is tagged with depreciation so, maybe someone else might take up making a new or updated road light someday.
