New Horn ???

I was curious is there any reason why I cant use a horn from a car/truck and add it to my bike ?
I mean as long as it plugs in the same and 12v. I dont like the little beep beep sound my horn makes.
I want something a little louder without going over board with it. Would I have to add a separate relay ?

btw my bike is a 97 Vulcan 800

thanks

Chevy trucks have two horns. A high and a low pitch. Get the low pitch and plug it in. No problem.

Thanks !

Bikes really do have wimpy horns. The little *eep eep* doesn't get anyones attention.

here is a good deal on another forum for a loud a$$ horn !

I put one of those on my Softail a few years back. It is a pretty good horn for the price.
