I got a Stebel 140db horn due to the recommendation of Bill L. (Pythias).
After hearing his horn I knew that was the one for me.
Mine came with a relay.

Here's the blurb:
<span style="font-weight: bold">
It's so loud, you'll make soccer moms on cell phones pull over to cry.
You will want to find a way to string 4 or 5 of these together for the ultimate MEGA HORN!
People won't know it's you who honked... they'll be looking for the semi truck.
That deaf old geezer driving slow might actually hear you now.
This horn is like a donkey kick to your ears!
Made by the world-famous Stebel of Italy, this true air horn kicks out 139dB of sound! For comparison, a gun blast is about 140 dB...
It's up to you to figure out the best way to mount it to your scooter. All it takes is 12v power and a good mounting point. Comes with a mounting bolt and a relay (if you determine you need it for your application).
Dimensions: approx. 5" x 4.25" x 2.75
