My 2024 Harley Fatboy horn sounded like a Toyota horn. I need a real horn. This one knocked it out of the park. Very easy to install. I buy all my lighting products from Custom Dynamics. They are excellent products. I was disappointed it was not in stock and sold out. I found one in stock on vendor who stock their products for the same price. Buy it you will not be disappointed.

Sounds great BUT...

The horn was easy to install and sounds MUCH better than Harley's stock "Miata roadrunner " squeak. However, be advised, the opening points straight out the left side of the forks and a direct hit with a water hose will kill it. Opening should point downward but saw no way to install it that way.

Great horn upgrade

Fit perfectly in stock location. Much louder and sounds like a car horn. If you’re considering it I highly recommend!

109 DB ELECTROMAGNETIC HORN

Great product! I have CD lights on my 2022 Heritage 114 and this was an awesome addition. 100% better than the stock horn. Tried other aftermarket horns (like Motohorn) but they required too much altering to fit and didn’t flow with the bike. This horn is loud, fits perfect, and looks clean with my Harley.
