Review on 🚛 Zento Deals 12V Single Trumpet Air Horn + Compressor – Powerful Loud 150db for Truck, Boat, SUV, Train by Phillip Jaylon

This thing is LOUD! The only problem is that the small pump that comes with it doesn't push enough. At $25 I can't complain much. I bought a Wolo 8088-C and discarded the pump that came with it. Note that you will need a 30 amp air horn relay if you want to use the standard steering wheel horn button. If you then sound the stock horn, that 12 volt can trigger the relay on its 2 pins, allowing more current through the direct battery wire to power the pump. You should be easy on the hands and have a basic knowledge of electronics. You also need a built in fuse right where you disconnect the battery + clamp. Not 1 or 2 meters away, right there. So if something rubs or frays, the fuse can blow and protect you from problems. Either way, it sounds like a tugboat or a fishing boat docking.
