Review on 📢 HK 12V 150db Air Horn, 18" Chrome Zinc Single Trumpet Truck Air Horn with Compressor - Powerful, Loud 150db for Trucks, Boats, SUVs, and Trains (Silver) by Erik Snyder

I needed an extra horn to make a mark. That's it. To be honest, I chose the trigger because of the price. Experiment. The wiring information can either be better worded or more descriptive depending on your point of view. However, You Tube solved it quite simply. Connected to a momentary switch it turned out to be exactly what I was hoping for. Right on the verge of obscenity. I will definitely recommend this device. * A notice. We have a lot of wasps in the area. I covered the horn hole with some window screen material to prevent squatters from interfering with the sound output.
