Customer Reviews

This is a great value for a seriously loud horn Review by ZooMan55
This horn may not look like much, but it performs great once installed. Installation on my 2017 Freewheeler was not super easy, but once I got it installed, it works well and sounds great (loud) approaching intersections and in traffic. You need the relay for stock Harley set up, but the stick horn button seems to work better and is more responsive to quick taps and double beeps than the stock horn was. (Posted on 8/7/2021)
