Non veni pacem mittere, sed gladium.
Everyone needs an air raid siren. I think that I'll give them to my grandchildren for Christmas....
12 Volts and loud...perfect.At 74 years old my hearing isn't good at all. Many times when I make a "shallow" turn in my car the signal doesn't shut off and I "unintentionally" cause people to be mad at me. So I'll get one of these, have my mechanic wire it to the signal "clicker" circuit and problem solved!
Back when this was a free country, I had a friend with a VW bug. He got cut off in traffic pretty often; so he installed an air compressor tank in the back seat so that he could run a truck's air horn.Traffic got out of his way after that! (Sounded more like a freight train to me, but it sure was loud!) Those were the days, and I sure miss 'em.
