I've got a call in to my districts code compliance office. I'm waiting to have that conversation before I do anything. I am in San Antonio. I like the idea about wearing down battery. Lights on my side were my initial reation, but I now think more light will not bother this guy. His backyard is already lit up like NYC all night long. I've also thought about extending the fence height temporarily with some wood supports and an ugly black tarp. See how he likes looking at that, my wife doesn't like that idea though.
