A working horn is a must-have for vehicle inspection and driving safety. This single high-tone 12V horn is designed to be paired with a second, low-tone horn (see Dorman part number 49325) to effectively replace a failed or missing original equipment car or truck horn. This horn comes complete and ready for installation with a mounting bracket and hardware and can be wired into an existing harness or a custom harness using the included connector. This snail-style horn generates a loud tone and is engineered from quality plastic to withstand heat and underhood vibration.
