Powered by the sun, even in the fog

It transpires that I'm not the only one whose sleep has been affected by the Huntington foghorn. After proudly announcing on Saturday that it was functioning again after three years of silence, the Coast Guard has had to admit that the foghorn on the lighthouse has been malfunctioning since it was turned back on and they've had numerous complaints from local residents.
Apparently it is now powered by solar energy (a very good thing) but is designed to stay on if it malfunctions, rather than shut down (a not so good thing for us). The last time it malfunctioned it sounded continuously for 41 days. Oh joy!
