Customers past and present impressed by reliable, durable technology and quality
Their characteristic tone has made Bosch horns a global success
Wide range of horns and fanfare available for retrofitting
With their distinctive sound, Bosch horns and fanfare ensure vehicles remain safe on roads around the world. Bosch submitted its patent application for the first electric horn 100 years ago in Germany. Right from the very beginning, drivers were impressed by the reliable technology in the legendary Bosch horn. Bosch now offers a wide range of horns and fanfare for motorcycles, cars and commercial vehicles; these products are characterized by their functional reliability, long service life and attractive design.
Robert Bosch GmbH submitted its patent application for the electric horn on April 12, 1914. During development, the company wanted the product to have a long range and a pleasant sound. The horn needed to reliably emit a sound as soon as it was activated, and low power consumption and an attractive design were also important prerequisites. The new Bosch horn, which came onto the market in 1921, met all of these objectives. The horn was based on the principle of "stopped pipes" used in organ pipe building. These pipes are closed at the upper end, so they emit a lower sound than open pipes. In the Bosch horn, this principle resulted in a pleasant and very characteristic tone.
Horns Produce Sound in All Directions — Fanfare Bundle the Sound Together The original design principle has remained unchanged in each of the successors to the Bosch horn that was patented 100 years ago. The sound is generated by an electrically activated membrane and is emitted in all directions. The product range has been extended to include fanfare. The funnel in a sounder is calibrated to a precise pitch and also uses a membrane to produce an exceptionally pleasant and soft sound that, unlike the sound produced by horns, is emitted in one direction. The unmistakable sound of Bosch horns and fanfare can now be heard on roads around the world.
Wide Range Available for New and Used Cars, as well as Retro and Classic Cars Bosch horns are available in a wide variety of models and variants for original equipment, individual design and special requirements for commercial vehicles, cars, SUVs and pick-ups.
Suitable products are also available for classic car enthusiasts. 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.
Modern inner workings ensure high performance with the best safety and durability, and almost completely recyclable
Reproduction launches with six different 6 V batteries
The classic Bosch black starter battery is now once again available directly from the manufacturer. As part of a reproduction project, Bosch Automotive Tradition has reissued the battery in its original design. While the battery exterior matches its historic counterpart, Bosch relies on modern technology and quality standards for the inner workings. Reproductions of the historic batteries therefore offer the same high safety standards and long service life as modern starter batteries from Bosch. The batteries can also be almost completely recycled. Initially, six versions of the black Bosch 6 V battery are available, costing between EUR 50 and EUR 210 plus VAT. There is the option of manufacturing 12 V batteries in the future.
Technological History: Starter Batteries for Passenger Cars Manufactured by Bosch Since 1927 Bosch was already producing the first batteries for motor cycles in 1922. The first range of car batteries followed in 1927 – hard rubber housing was still being used then. In 1955 black plastic housing was initially provided for motor cycle batteries, and Bosch converted from hard rubber to plastic housings for its passenger cars in 1962. The classic black design was finally replaced in 1966 with the introduction of direct cell connectors.
Thanks to modern technology, the batteries reproduced by Bosch Automotive Tradition featuring the historic black housing provide starting power that is up to 70% more powerful than the original battery. In addition, the batteries are more stable and almost completely recyclable. The reproduction of the black Bosch original battery design means that an important spare part is now available, allowing engine compartments of classic cars to reclaim their original appearance.
Parts, Expertise and Passion for Vintage Car Enthusiasts In addition to reproducing parts according to original manufacturing documents and repair concepts, Bosch Automotive Tradition, the Bosch Classic Division, offers a comprehensive knowledge database, including installation instructions, lists of equipment and spare parts, and links to possible spare products, recording tables and usage records at www.automotive-tradition.de. Fans of classic cars can also find rare spare parts and discontinued products from Bosch via the online shop partbob.com. Bosch Automotive Tradition is also involved in classic car fairs and rallies with vintage cars.

"Back to the roots" is the theme of the 15th anniversary of the Bosch Boxberg Klassik held this year. Bosch classic car enthusiasts had organized the rally for the first time 14 years ago as a one-day event based round the Bosch Boxberg test center. At the time, the rally was still in-house.

The start and finish line is the Boxberg Bosch test center, where participants then face challenging special stages. As it is every year, the highlight is a parade of all vehicles on the high-speed oval test track at the test center. A colorful program of entertainment awaits visitors including food and drink, provided by Windischbuch, the local sports club.
