A working horn is a must-have for vehicle inspection and driving safety. This metal 12V horn can be used to replace a failed or missing original equipment horn on a car or truck, or to add one to a motorcycle, scooter, ATV, or golf cart. Its metal construction helps generate a loud, high-pitched single tone while withstanding vibration and underhood heat. Simply connect it to an existing wiring harness using the included corrosion-resistant, cadmium-plated mounting bracket that allows various installation locations.
