Being south of the border, you might not have these there. If you look at the lights arm attached to the Telco pole, you will see a small box. On that box is a little piece of wire sticking out of it. The box is only about 1-2 feet long and about a foot deep. I just happen to know what it is, but I wonder how many others do.
Hint: It has to do with telecommunications.
Answer down below.
Answer: It is a telephone repeater box. It picks up the signal from a cell phone, sends it over the telphone wired system to the nearest cell tower, which then sends it from cell tower to cell tower. It gets it's power from the electric eyes for each street light.
