About Horns

The BMW horn is an electromechanical apparatus fitted in the car which produces a loud noise, intended for use as a warning signal. The horn would be applied in an emergency situation, with the intention of avoiding a possible accident or a dangerous situation. The horn should only be used as an alert to other road users, to inform them of your presence.

The horn is usually housed in a metal casing, which acts as an amplifier, and situated under the bonnet in the engine compartment, behind the front grille. It's normally secured in a bracket which is bolted into place. The horn should be fully functional with all components fitted securely and in good working order. The design of the front grille is usually such that the sound emitted from the horn can travel and dissipate through it and out of the car, enabling it to easily be heard by other road users. The controls to operate the horn should be within easy reach of the driver and working properly. The horn is usually operated by a control on the steering column stalk or by pressing a button in the middle of the steering wheel. There are many different horns on the market with a variety of sounds. To ensure a product that complies with MOT regulations and one that will be a simple to fit and suitable for your car, it's worth buying the BMW horn which is designed to be compatible with the make and model of your vehicle.

There are typically two types of horn used in passenger motor vehicles but both work using  a diaphragm, normally constructed of spring steel, which vibrates to produce the sound. A higher frequency/HF horn has a diaphragm with a resonator plate fixed to it which serves to amplify the sound. A windtone horn uses a trumpet design which amplifies the sound when the diaphragm causes air to vibrate through it. Both types use electromagnetism, with the use of a coil wire which makes an electromagnet, to make the diaphragm vibrate which produces the sound. Essentially, the horn has an electrical contact which is attached to and activated by the diaphragm, and works with an electrical current sourced from the car's battery.

Because of their location in the vehicle, horns are subject to damage from water and dirt which can cause the electrical connections and mounting bracket to corrode. Rust is a common cause of a malfunctioning horn. Faults can arise with the circuit, cables and connections, the horn itself or the operating switch. It's important that a broken horn on a vehicle is replaced as soon as possible. Buying the BMW horn will guarantee you get a part that's manufactured for your specific car make and model, giving you the ideal replacement that will fit well and perform properly.

BMW trivia

• Think you know what BMW is an acronym of? If you answered Broke My Wallet, you’re definitely wrong. It really stands for Bayerische Motoren Werke (which is Bavarian Motor Works in English).
• That distinctive BMW car engine sound that new owners fall in love with might not be real. The BMW M5 has such a quiet engine that they had to install fake engine noises to keep drivers happy!
• The BMW M1 has a classic look, so it's no surprise that its designer also came up with some other amazing car designs. Giorgetto Giugiaro is also responsible for the DeLorean, the Beretta U22 Neos handgun, and the Nikon D4 camera! Although, he also designed the Yugo, commonly called the worst car that's ever been made.
• The Cold War affected BMW sales so significantly that the company was nearly bought out by their arch-rivals Mercedes in 1959. A silent investor saved the company, but the rivalry between BMW and Mercedes Benz is ongoing.
• Everyone knows what the BMW logo looks like, but do you know what it represents? Most people think it's inspired by propellers (because of BMW's aviation history), but it's really just the same colour scheme as the Bavarian flag and was designed to showcase Bavaria.
