My motto has always been "One is able to attract more bees with honey." If you feel the need to go over to the bright light house why not take the friendly approach? You may want to start off with why you are the complaintant instead of their neighbors, then be friendly and see if they are willing to compromise. A motion sensor may be the perfect solution.

Even though we do live in a low crime community it doesn't mean we should all leave our doors unlocked and lights turned off at night. To each his or her own, I myself feel the need to be prudent when it comes to safety.
