Recently in my town they have been replacing the street lamps. I could be over thinking it but I thought fuck it I’m going to ask them what they are doing. Apparently they are converting them to energy saving bulbs, I questioned as to why they need to replace the whole top of the light and why it’s now got an aerial on top they couldn't come up with any reasonable answer. I’m convinced it’s do with the 5g rollout which is coming soon
