China Horn Assembly Suppliers
A horn is a sound-making device that can be equipped to motormotorcycle and scooter, and other types of vehicles. The sound made usually resembles a "honk". The vehicle operator uses the horn to warn others of the vehicle's approach or presence, or to call attention to some hazard. Motorcycle, scooter, others vehicles, ships and trains are required by law in some countries to have horns. Like trams, trolley cars and streetcars, bicycles are also legally required to have an audible warning device in many areas, but not universally, and not always a horn.
