One More Light!

As noted in the last post, every example of a non-American traffic light was always posted on a pole and never hung by wire across an intersection. I speculated the reason for this was that other countries, Europe in particular, prefer to lay power lines underground rather than hang them from poles. Therefor, perhaps this extended to traffic lights as well: Countries were either unwilling or unable to hang them from wires since they were not above ground to begin with. However, I recently obtained a photo from Chile which counters this theory:

Although the image isn't very clear, it is quite obvious that the traffic light is suspended by a pole, in complete defiance to above-ground power lines along the very same intersection.
