I've got the horn

[The Prophet of Doom]

Installed my new horn yesterday.
it's a Stebel Nautilus Motorcycle 2nd gen (Black) $87NZ ($USD68)

A very simple install just by drilling a single hole in the headlight bracket, relay onto the dashboard mount, and a bit of backyard crimping.  It tucks neatly into a spare space so it will never be seen.

139db @ 1 meter - this is a seriously loud horn - sounds like this http://www.stebel.it/stebel2009/suoni.asp?IDsuono=slnautilusCS.swf

I mounted 2 horns from a junkyard Ford Taurus under my fairing. i learned very quickly that it needed a relay after i melted the spring under the horn button (i had a sutable replacement spring)... they are LOUD too...

oh & cost about $12  $4 ea for the horns & $3 plus tax for the relay.. :)

I've got a rubber squeeze bulb horn. It doesn't make sounds as sophisticated as your high dollar tooter.     BDC

I saw those in a kit... came with a zing-zing bell and pretty tassels for the grips, lol  ;D ;D
