Says Peter Heinrich Chief Engineer IBM W: "Trumpets regular electromagnetically used cars in some of the country may not last more than two or three months."
And although the car horn is a simple piece, but it does not allow any car to go on the road without them, however the centenary of the invention by the German manufacturer BMW has not seen any significant changes.
