Wow, those are long horns.

The Stebel air horn is much more compact and easy to find a mounting point. A few other horns that look like the Stebel are not as loud and some are even a waste of time.

A pair of electric Fiam horns are quite loud and are not too spendy. I did consider them originally till I heard a Stebel horn.
