Our bulb taxi horns and bulb horns are brass and come with the old fashioned black bulb. In 1899, France became the first country to pass a law requiring automobile horns. Soon the curled brass horn with a rubber bulb became stereotypical of the early cars. Our bulb taxi horns and bulb horns are reminicent of these old fashion taxi horns used before air horns became readily available. Perfect for calling in the kids or just tooting your own horn!
