Whistles

[Alloneword]

Lomg story but i'll try to keep it brief, riding round London on the bike most people seem to ignore the bike horn or even the odd f**k off, so was looking at another way to make dozy van/Black cab and pedestrians pay some attention and i came across a police escort a while ago who done away with sirens and used whistles like a football ref, so done some digging and pulled over and spoke to one of these guys when i say him parked and and found out they buy the whistles form a site called www.acmewhistles.co.uk spoke to them and bought what plod uses, however it turns out i must have a fat head as when lid is on and whistle is in place the whistle keeps hitting the chin guard of the lid so is not good my whistle's spec is Dimensions: 4.5(L) x 1.8(W) x 2(H) cms but i need something more like 3.5cm long, I know it's very anal but i'm an anal kind of guy (don't go there) about this stuff, so anyone know of any other sites that may be of use to me?

Why don't you buy one of those compressed air horns?  A while back, I saw a spot on the internet where someone showed how to make one out of an old prescription drug bottle.  Just a thought.

It's to do with timing, if you need to alert someone you are there then having a whistle in your mouth all the time is a quicker way to alert someone rather then having to move your thumb from the grips to the horn button it's fractions of seconds but they say it helps, so going with their knowledge as they know more then me.
