Bosch’s horn program spans more than 80 part numbers

<p>Bosch offers a wide range of horns and fanfares (a signaling device that can be used as a replacement for horns) in a variety of models and variants for cars, SUVs, pick-ups, motorcycles and commercial vehicles.</p>

Robert Bosch LLC’s horn program includes more than 80 part numbers, offering disc-type horns as well as fanfare horns and compressor trumpets, and even a backup warning signal.

Depending on the type of horn, voltage ranges from 6-volt to 24-volt, with frequencies from 300Hz to 840Hz. Many of today’s original equipment manufacturers – domestic, Asian and European specify Bosch horns for their new vehicle production, according to the company.

Bosch horns and fanfares are also available for classic cars. Bosch Automotive Tradition, the classic division of Bosch, gave the famous Bosch horn a new and historic redesign in 2006, including slotted screws and chrome-plated horn covers. The original was used in many vehicle brands and models from the 1950s and 1960s.

What’s the difference between a horn and a fanfare? While a horn emits sound in all directions, a fanfare emits sound only in the direction of travel. The funnel in a sounder is calibrated to a precise pitch and also uses a membrane to produce an exceptionally pleasant and soft sound, which, unlike the sound produced by horns, is emitted in only one direction. Bosch’s product line also includes fanfares for cars, SUVs and pickup trucks.

According to Mary O’Halloran, senior product manager for Bosch’s Automotive Aftermarket North America division, “Bosch horns are the perfect complement to the complete range of Bosch aftermarket replacement parts. They have a long history of helping to bring safety to the roadways of the world; and their quality construction, reliability and characteristic sound are trusted by OEMs, technicians and motorists alike.”

Bosch filed its patent application for the first electric horn in Germany in 1914.
