Bike Warning Device Wanted
I have found this site while conducting an occasional (fruitless) search for a decent bike warning device. I can't believe nobody has thought of making one that will, for instance, penetrate a lorry (truck) cab. I ride off road (as far as possible) around the Surrey (UK) countryside. I hope I am starting a thread which will generate some interest, particularly with someone who makes stuff for bikes!
I want an electronic three tone push button horn:
1 is a chime - friendly warning to pedestrians, walkers on trails etc.
2 is louder and shriller as a more urgent warning (car squeezing you into gutter etc)
3 Is fierce for emergency only - You are about to kill me!
I know this was possible in a small device at least 20 years ago yet no one seems to make anything that fits the bill. Dpes anyone know better? Do any manufacturers watch this site?
