Horn grille

A horn grille is a part of some designs of automobile or other motor vehicle that has an electric horn, such as a motor scooter.

The radiators of modern cars no longer determine their shape of the grilles, which have become more abstract, the radiator being of different proportions from the grille and over 15 centimetres behind it. Usually grilles are now designed such that the sound of a horn can readily come out through them. But those designs which maintain the notion that the shape of the grille shall reflect the shape of the radiator behind it no longer have front fenders with rather large crevices which would permit the old trumpet-shaped horns to be mounted on top of them. Thus some cars, often British ones, have a pair of round horn grilles mounted on either side of the radiator grille, behind each of which a horn is located. A luxury car's horn grilles are usually chrome-plated.

Cars with rear engines, such as the Volkswagen Beetle and the early Porsches, necessarily have no radiator grilles in front, and so have horn grilles placed below their headlights.

Some motor scooters have this feature as well, placed below the handlebars. Their horn grilles may be cheap plastic. These vehicles and the cheaper cars have only one horn.
