Review on 📢 GAMPRO 12V 135db Air Horn, Dual Trumpet Air Horn with Compressor, Extremely Loud Train Sound, Shiny for 12V Vehicles, Trucks, Lorrys, Trains, Boats, Cars, Vans by Brent Webb

This is a mixed review to begin with. I liked the horns when they worked because when I ran it in parallel with the 18" set at 150dB it really sounded like a train. The three horns together were very loud and it was fun to drive down back roads away from houses honk (it was LOUD), all of a sudden all I got was the sound of my Mac truck horn from my 18" horn. My guess is that after a week or so the compressor blew up just humming back and forth. My electrical system is non-standard, it has been completely redesigned and runs at around 13.8 volts nominal (which is good) and I had no problem getting the horns to work. But then again, out of the three, only one works for me. It was under $20 so I'll probably buy a better set next time, but if you're looking for a bit of fun then this horn is for you (note this pair is quite a high note)** Update: replaced the compressor only to understand that the airflow in the tubes was blocked and the compressor burned out due to a stalled engine. I still sound like a truck.**
