baph--The complexity of using air on a bike is hardly worth the problem You will have a tank/compressor which would be quite heavy and air trunking plus the tank is going to be so small it would probably only let you have a very short blast Would it be easier to fit a pair of the already recommended horns with directional trumpets

Mint ! I was honking away for ages ! :lol:
Simple thing please simple minds I guess :lol:

How to wake up the neighbours;

Go to the Stebel website, hook up the laptop to the very loud home cinema system, turn volume up to 11, open windows and start honking! :smt046 I honesetly thought I would wee myself laughing watching next door duck for cover. :lol: :lol: :lol:
