Horn

Heavy-duty vehicles get an exciting, head-turning accessory and show-stopping sound from the Wolo Cannonball Express Truck Air Horn. This sleek truck air horn borrows its intimidating design cues from modern, loud railway horns, and has three chrome-plated trumpets. The outrageous 125-decibel sound output is matched by the beautiful chrome finish that complements any vehicle. Only vehicles that use onboard air systems can use the Wolo Cannonball Express Truck Air Horn, so it's recommended to upgrade to the Wolo Turbo Tank & Compressor. Your purchase is backed by a 1-Year Warranty.
