Review on VEVOR 150DB Train Horns Kit - 4 Trumpet Air Horns with 120 PSI 12V Air Compressor and Tank, Super Loud for Trucks, Cars, Jeeps, SUVs (Black) by Agonia Ajdini

Worked 4 hours. I installed it with a switch and a button. All tests worked. Had a good tone and raised eyebrows. I went to show my friends and nothing. I even tried plugging it in so they could hear it and nothing. I have a connection and the button even works, but no sound. everything is good in the package. But I strongly advise against pipes and 2.6ft hoses! Compression flows through the clutch and you will often hear the compressor filling up! But even after 4 hours of pipe installation at full 125psi and a good connection, no sound at all! Will return!
