Review on 🦏 Hadley Horns H00640R 14 15/16 inch Dual Tone Black Bully Horn by Mike Donathan

Hadley horns are of fairly good quality and have been used on Mack trucks for years. It has a very unique sound that you can definitely hear. Also known as a Hadley Bully, this type of horn is made of metal and is typically an under cab horn and requires a mounting bracket to attach to the underside of the vehicle. I mounted it to the underside of my Chevy S10 with a Mack MRU garbage truck mount and installed an air compressor and 12 volt solenoid to make it work. Sounds amazing!
