Hi everyone. This isn’t project-related but just always been curious and thought someone on here would be able to give me an answer. Sometimes I see three small coloured circles on hydro poles and I was wondering what these are. They are usually at street level, about 7 ft from the bottom of the pole. I’ve seen green, blue, white, and red. I have attached a photo showing an example, next to the no stopping sign.
Can anyone tell me what these are for?
Thanks!
