I really don't know where to begin. I've read this whole thread. It reminded me why I took a hiatus from BikeForums. There were a couple of lone voices in the wilderness preaching wisdom re: the necessity of an AirZounds. I've been riding for decades without one. Or any kind of horn for that matter. They are necessary in some states to be legal. We have one on our tandem. I put it on the stoker bars so my SO could entertain gawkers. I never have known what the horns on any of the cars I've owned sounded like. I've never used them! When I want to say hi to someone I flick my brights at them. You are on borrowed time if you really believe it was your big, bad, airhorn that kept that clueless soccermom from nailing you. Likely you also scrubbed off a little speed or took some other kind of evasive without even thinking about it. As you should. The horn was to work off anger. Did it work? Nope, because next day (same day?) you are here telling the forum about it. If the OP wants a bell the Incredibell by the Mirrycle people should do fine and last forever. The mirror they make is also pretty darn good. I like bike mounted mirrors but they can get busted if you drop your bike (I don't, it falls over on its own). I love the super large (2.25" diam) helmet mirror by Efficient Velo Accessories. I do not believe in multiple super bright rear flashers. One flasher for the bike and maybe another for the back of my helmet, whatevers on sale and/or cheap. Planet Bike makes good stuff in this category. Onguard Akita Cable Lock if you live outside NYC. If you live in NYC do not lock your bike, get a folding bike and keep it with you at all times.
