1.       Replace fixture: The fixtures are Sea Gull Lighting 88201-12 Two Light Black wall lanterns. The manufacturers suggested retail is $155. They can be found for $100-$120 both on the internet and from stores. The web page for the fixture is:


2.       Replace light sockets: Sea Gull lighting tech support told me they do not sell a replacement socket and do not "support" replacing the sockets. The fixtures at $100 a fixture, are mostly aluminum castings with glass lenses, some wiring , and the two light sockets. None of my four lights would work, so I would have needed to replace both fixtures at a minimum of $200 plus tax for parts. I did some searching and found a socket that is at least as good as the original socket. Here is a link to the replacement socket available at Lowes:
