Toyota Genuine Premium Horn Sound check confirmed before listing. It was working properly. There is dirt and rust. Please check the images. Can be installed directly on Toyota vehicles. (For vehicles with 2 horns) If the horn doesn't sound after installation, please try cleaning the metal parts of the vehicle's mounting area and the horn's bracket with sandpaper. Shipping will be via Yu-Packet Plus. Please refrain from bidding if you are overly concerned about details. Thank you.
