I've been doing some research on electric horns/bells for my commuter bike. I'd like to find something that sounds more like a scooter or even a car horn (not as loud, just a similar type of sound) than the traditional ding-dong bicycle bell.

I found this QBell electric buzzer made in Korea:

I have not been able to find any more references to it, nor have I seen it sold on eBay or CraigsList.

Has anyone heard of that particular gadget, or does anyone know of an outlet where they would sell it? Any information will be greatly appreciated.

Just as an additional reference, these are the other electric horns/bells I've been looking at:

Most marine or larger sporting goods store have these.

Wow, thanks for all this collection! I use such a horn.

A 6 volt automotive horn? How did you mount it to the bike? Do you use a regular 6V battery?

Here's another horn I forgot to include: the Verbal Bicycle Bell

The horn is attached to my front rack - incidentally details of the attachment matter for the loudness, which I found the hard way, given that one deals with an acoustic radiator. It is powered by five 1.2V AA rechargeable batteries. The latter are charged by the dynohub, but that is a separate story. I put the switch onto the handlebars next to my thumb. Handlebar switches are available for mopeds and motorcycles but I ended up making one of my own.

Thanks for all those links. You should maybe put them on some page of yours to increase the return on your investment. While people may google out the collection here, on that page you could keep them updated.

It's not electric, but a friend of mine has an Airzound. It will get your attention.

We were on a fast descent which has an intersection at the bottom. He was in the lead, and a car made a move as if it were going to make a right turn into our lane. He gave a blast on the Airzound, and the car made a very quick stop.
