Review on 🚂 Powerful HK 12V 150db Air Train Horn Kit with Compressor - Loud Single Trumpet Horn for Trucks, Cars, Boats, SUVs, and Trains (Black) by Chad Mills

If you are looking for something other than a reservoir and compressor air horn this is the best I have found so far. it's no Kleinn, but it's no 300 either. In case you didn't know, the longer the pipe, the deeper it is. I think it's 16.5 inches, and anything over 16 inches is what everyone needs. The electric compressor seems a bit bigger than most standard compressors so I was skeptical at first, but the sound isn't that bad. Once you know what you're doing, installation is easy, just press the button with the instant beep. Installation took about an hour and I was just looking for a place under the hood
