Horns for traffic are a must for me. I've been using AirZound horns for almost 20 years. They are air horns that you pump with a hand pump to charge. They use a soda bottle like bottle for the air reservoir.

I'm surprised air horns aren't more popular. That work to alert cars, even when their windows are up. They often deter dogs, and scatter cats and squirells in your path. I have a short one-vehicle-at-a-time tunnel on one of my routes and I blast my horn to alert cars when I pass through.

Bells and a friendly voice for pedestrians, horns for cars!

BRILLIANT!!! in it's simplicity. Love the idea of a refillable canister of air as "bg" suggests. =)


Like bg said, AirZound is great. It comes with a tube and a bottle to store the compressed air. If you have a spare bottle cage, you can just put it there and forget about it. Here is my setup: http://i.imgur.com/UDsjE.jpg


If you get the chance, could you post more pictures so I see how the whole thing is built and set up? Thank you.
