Good, I thought as much. But in many cities I still see street lights comming on at the same time making me think that they are operated by a centralized timer or a daylight switch. But I get the point.
itsmoked Did you understand what HCBFlash explained about twist lock. A I mentioned we have normal lamp posts different from the ones they use in the city streets. Unless there is something I need to learn.
