"Finally, one day, my neighbor asked me if I ever had any trouble with my outdoor lights. I told him yes, as a matter of fact I did. I said that they would loosen up occasionally and I would have to retighten them. I blamed it on vibration from the traffic on our street. He said that he had the same problem. I told him that I finally just gave up and left them off. He eventually did the same. We were happy with the final outcome and we were able to keep peace in the neighborhood."
