This is a test done at Angeles Crest Highway in Southern California. The horn is a Zollner ZM200/90. It is mounted inside my Scion XB facing the rear (the horn you see on top of the roof is my Ibuki Kogyo Class II ship horn. Visit my channel to see the Ibuki video). This horn carried the sound so far that people miles down the hill thought that some kind of truck had gone over the side of the mountain and is honking the horn for help. I was told to pack up and leave. This horn is usually found on cruise ships.
