Abstract: A vehicle horn has a shield which covers the mouth of the horn's bell to prevent debris from entering the bell. A front sound opening beyond the bell mouth perimeter allows sound to project forwards while still protecting the bell and a rear sound opening aligned with the front sound opening allows debris to pass through both openings without collecting within the space between the bell mouth and the shield. A side surface shields that space and includes a bottom cutout which allows any debris collected to fall out of the space. A vehicle horn has a bell constructed of two tubular sections, the end of each section having a mating flange which fits into a specially adapted clamp. As the clamp is tightened, the tube sections are drawn together until they butt against each other. The clamp is tightened by securing mating collar portions against each other. A pedestal and a rear mounting base are used to connect the horn to a vehicle. The rear mounting base and a mounting bolt are connected to the vehicle.
