Horns and fanfares

Powerful sounds meet robust technology – a wide selection of sounds for safe signalling in road traffic.

For which vehicle is the horn intended?

From cars and transporters to motor homes: The vehicle electrical system is crucial – this is usually 12V in cars and 24V in larger vehicles. The choice between a 12V signal horn and a 24V dual horn therefore also depends on the area of application.

What is the horn for?

Is it simply a replacement, or is more volume or a more customised acoustic pattern required? While the classic 12V signal horn sounds more concise and functional, the 24V two-tone horn delivers a full, distinctive sound – popular with tuning enthusiasts.

Does the horn have to be approved?

This might seem like a banal question, but it's crucial: Not every fanfare can be used in road traffic. HELLA offers numerous ECE-approved models that are legally compliant and roadworthy – without compromising on sound quality.

Classic solution for cars and transporters

The 12V signal horn is the standard solution for most vehicles – and ideal for drivers who value functionality, safety and straightforward retrofitting.

Easy to install

Many HELLA models can be easily mounted on existing holders. The 12V horns come in a range of compact designs which makes them particularly flexible – and can be accommodated in the engine compartment even when space is limited.

Ideal for everyday use and replacement

Whether you are replacing a faulty original horn or performing a specific upgrade – the 12V horn makes it all worthwhile owing to its durability, clear sound characteristics and tested quality.

Powerful sound with character

Two tones, one acoustic pattern: The 24V two-tone fanfare – or two-tone horn – ensures an unmistakable acoustic presence – popular with motorhome drivers, pick-up owners and classic car fans.

Ideal for larger vehicles and tuning

Compared to the single tone group, the two-tone horn produces a voluminous sound. Ideal for 24V vehicles or drivers who want to make themselves clearly heard.

Technically robust – with style

HELLA dual-tone horns are not only powerful, but also designed for durability and demanding operating conditions. Whether rain, dust or dirt – they deliver reliable performance.

Proven brand quality

HELLA stands for tested safety, sophisticated technology and many years of experience. Our horns and fanfares are installed worldwide as original equipment – and also offer genuine OEM quality in the aftermarket.

Diverse selection – for every application

From the compact 12V horn to the loud 24V fanfare – the HELLA range includes suitable models for many vehicle types and installation requirements.

For all those who want more

Whether classic replacement horn or upgrade for more expression: With HELLA, you can count on reliability, easy retrofitting and convincing sound – whether on or off-road.

What is the difference between a horn and a fanfare?

A horn produces a single, clear sound – compact, functional and legally prescribed. A fanfare (e.g. two-tone) combines two tones to create a more distinctive sound – ideal for more acoustic presence or individual tuning.

What voltage do I need – 12V or 24V?

This depends on your vehicle's electrical system:

• 12V is standard for transporters, and motor homes.

• You will find 24V in lorries, buses or larger commercial vehicles.
  Tip: You can clarify the situation by looking at the operating instructions or the battery.

Is a two-tone horn permitted in Germany?

Yes – provided it has an ECE approval (e.g. E1 marking). HELLA offers many models that are road legal and are compliant with the German Road Traffic Licensing Regulations (StVZO). This way you err on the safe side – also during the main inspection.

Can I install a HELLA horn myself?

In most cases: Yes. Our 12V and 24V horns are compact and are supplied with well designed holders which makes them easy to retrofit. Important: Switch off the ignition before installation and ensure that the wiring is correct. If you are not sure how to proceed, ask the workshop.

How loud can a horn actually be?

Road-legal horns are usually between 100 and 118 decibels – enough to be heard without causing annoyance. HELLA models are fine-tuned to sound clear, assertive and be compliant with the regulations.

Are there differences in sound between 12V and 24V horns?

Yes – 24V dual-tone horns often seem fuller and more powerful, simply because they are intended for larger vehicles. A finely-tuned 12V horn is usually sufficient for cars and transporters – both are available from HELLA in harmonised quality.

What if my vehicle doesn't have space for a large fanfare?

Not a problem: HELLA also offers compact models that can be easily accommodated – e.g. in the engine compartment or behind the bumper. Sets are also available with relays, brackets and cables to make installation even easier.
