One of the little requirements about my community is you are required to have a yard light and said yard light must have an arm that displays your street address. This is for safety, so the men coming to kill you will find the right address and not attack some innocent bystander. My yard light quit working about a month ago. Try as I might, I can't figure out what's wrong with it and don't really want to pay some and to come out. So, my solution was to pitch the old bulb and buy a solar light and drop that into the place where the old light bulb went. Voila, I got a yard light that works.
