I must also suggest contacting the offending neighbor. In my five years in TV, I have found that almost all the social restrictions we seem to have lived with "at home," (among other things, that may include "don't ever contact a neighbor who has bothersome lights, dogs, habits, etc., because that may stir up trouble"), go by the boards here in TV once folks recognize that a friendly word here and there may work wonders!
Our formerly rather insular lives do not / should not apply here in TV!
Whatever, Happy New Year!
