Well, went to get a few bits for the air system today and came home with this as well...

Went to a place called 'Air On Board' - Air On Board - Home - they have a great range of everything you may need to get air sorted in your vehicle, and were very friendly and helpful. They showed me - and operated:) a few different air horns including the set I showed a link to in a previous post - man are those things loud... Too loud for a vehicle IMO - they made the ground vibrate and were absolutely deafening. I settled on the good old truck horn - nice low note and although it is loud, I shouldn't get hassled too much by the law if using it. Not sure where it will be mounted yet, going to work that out later, once I've got the compressor hooked up and working.:)
It was $80 including all lines, wiring, relay, switch and fittings to get it going, which isn't bad IMO.
