You need to know what you are buying here. It's not the beep you hear on semi-finished products. These horns require an air compressor and the horns themselves are much larger. These settings cost a few hundred dollars. However, for $30, it's definitely an upgrade. I used a decibel meter on my phone. My stock horn (a 2015 Jeep Wrangler) read about 50-55 dB. This horn was about 74-77 dB. It's definitely louder. Also, there is no "promotion" or anything I've read from some people. When I touched the hot wire to the + terminal, it immediately started hissing. I have no plans to change the wiring, just using it as an extra horn, but will update later to report on its durability.
