The Horn is something that has been seen in cars for decades, but can easily be the feature that is used the least. The horn is a device that makes a loud sound, that can be used for grab attention. The horn is installed in the engine area of the vehicle, and can be easily identified due to its being shaped like a horn. The horn system is found on the steering wheel, while the outer system of the steering wheel is used to turn the vehicle, the center of the steering wheel is a horn. This is a button life feature, as the driver is required to press on it to make sound. The size and sound intensity of the horn depends on the car and its model, but the location of the horn is only different in vintage vehicles, where the horn was attached separately; and needed to be squeezed to make sound.
