Review on 🔊 Enhance Your Truck's Audibility with the Wolo (845) Road Warrior DD Roof Mount Truck Air Horn - 12 Volt! by Alexander Scharon

This horn is a good buy at $50-70. The box arrived quickly and in good condition. It contained the correct product, instruction manual and some fasteners. Note: If you install this horn in any other way, be aware that it is very large. I didn't want to make it visible and found it fit nicely under my car's rear bumper. Installation took very little time, the instructions are simple and all the necessary hardware was included (except drills). The sound is very loud and works well. The compressor takes about 1/4 second to build up pressure from the moment the button is pressed. I do recommend getting a better switch though, I got the switch at my local hardware store for less than a dollar and it works much better than the one that came in the kit. The schematic is complete and the wiring is very simple.
