Call the FAA. But I can tell you they won't do anything about it. I worked at a radio station whose 500ft tower was dark for nearly a year and it was within 5 miles of the airport. Nobody did anything about it being dark. It was almost a year before it was lit again.
Not unusual really.
Once officially notified to the FAA, the issue becomes a notice to all filing flight plans anywhere near the tower (mostly General Aviation, not high altitude commercial) as an information item. It may or may not be on regional NOLAs but locals definitely need that info. While some large market stations may have a tower firm (independent from the radio station CE(s)) those folks are usually regional, expensive, and run ragged. It can easily take up to a year for them to get around to a smaller station on the que and replace the light(s).
One FM I worked at in NC had a 1,500' tower. It took a good 9 months for them to get to us and when they did the three man crew split $15 grand to replace two beacon lights and replace a transmission array bay (half the size of a hula hoop) that was pitted to beat the band with lightning strikes. That was 1995 money. Gonna be more now.
