Used Truck Air Horns 24V – DAF, MAN, Volvo, Mercedes

Used 24V truck air horns for European HGVs

Exterior air horns on a heavy truck are critical safety components. They provide a powerful, highly audible warning signal in traffic, around depots and on motorways, helping to protect drivers, pedestrians and other road users. On modern European lorries, 24V electric-pneumatic air horns are mounted externally on the cab roof or front area and are designed specifically for each truck brand and model.

In this category we offer used OEM 24V truck air horns removed from complete donor vehicles. Typical examples include electric-pneumatic air horns for DAF XF/CF and Mercedes-Benz Actros, as well as horns suitable for MAN, Volvo and other popular European trucks.

What you will find in the Horns category

Stock in the Horns category changes as new donor trucks arrive, but it typically includes:

• 24V electric-pneumatic air horns complete with mounting bracket and connection for air line and electrical feed;
• single and twin trumpet air horns designed for roof or cab-front mounting;
• brand-specific horns tuned and shaped for DAF XF/CF, MAN TGX/TGS, Volvo FH/FM and Mercedes-Benz Actros;
• selected compact 24V air horns that fit behind trims or in protected locations on the cab.

Each listing includes clear photos, OEM part numbers where available and donor vehicle details so you can compare trumpet length, mounting style, electrical connector and air line connection with the horn fitted to your own truck.

Truck brands & typical applications

Most air horns in this category are taken from mainstream European heavy trucks, including:

• DAF XF and CF series (for example DAF XF106 air horn assemblies);
• Mercedes-Benz Actros tractors and rigids (including popular Jericho-type air horns);
• MAN TGS and TGX long-haul and construction trucks;
• Volvo FH and FM long-distance and regional haulage trucks;
• other brands such as Scania and Iveco when suitable donor vehicles are available.

Because these are genuine OEM parts removed from complete trucks, each horn can usually be linked to a specific model generation, cab type and Euro emission class, which is important for achieving the correct fit and sound output.

Why truck air horns matter

A correctly functioning air horn is essential on a working HGV:

• Safety and awareness – a loud, clear horn allows the driver to warn other road users or workers around the vehicle quickly and effectively;
• Compliance – commercial vehicles must have an operational audible warning device that meets local regulations and inspection requirements;
• Professional presentation – matching OEM horns keep the cab looking tidy and prevent empty brackets or non-standard fittings.

Compared with many universal horns, OEM 24V truck air horns are designed for long service life, correct integration with the vehicle’s air and electrical systems and a sound level appropriate for heavy vehicles.

Typical reasons to replace a truck air horn

Common reasons to order parts from this category include:

• horn not working at all due to internal failure, water ingress or damage;
• weak or intermittent sound caused by worn internals or air leaks;
• physical damage to the trumpet or housing after contact with low bridges, trees or loading bay structures;
• corroded brackets or fixings that no longer hold the horn securely;
• replacing a non-original or universal horn with the correct OEM air horn for your truck brand and model.

How to choose the correct air horn

To minimise fitting issues and ensure the right performance, please check the following details before ordering:

• truck brand and model – for example DAF XF106, Mercedes Actros MP2/MP3, MAN TGX Euro 6, Volvo FH4;
• voltage – most heavy trucks use 24V systems; always confirm this before ordering;
• horn type – electric-pneumatic air horn with trumpet(s), compact air horn or other design;
• mounting position and bracket style – roof-mounted, cab-side or behind a front trim, and how the bracket attaches to the cab;
• air and electrical connections – size and orientation of the air line connection and type of electrical connector or terminals;
• OEM part numbers on your original horn body, bracket or label, matched against the references shown in the product description.

If you are unsure, you can contact us with your VIN or registration number and clear photos of your existing horn and mounting area. Our team can help you confirm compatibility before you place an order. For general guidance, see How to Find the Right Part and Compatibility & VIN Policy.

Used OEM horns from dismantled trucks

VRA Truckparts specialises in used OEM truck parts sourced from carefully selected donor vehicles. Trucks are inspected and documented before dismantling so that cab and exterior components, including air horns, can be assessed. During dismantling, our technicians remove the horn assemblies, check the housings and brackets for obvious damage, and reject units that do not meet our standards. Usable parts are cleaned externally, labelled and stored under cover in our warehouse ready for dispatch.

Because these are genuine OEM components designed for heavy trucks, you benefit from the correct sound output, durability and mounting interface for your vehicle. To learn more about how we work, please visit Our Dismantling & Quality Process, Warranty & Part Condition and Trucks We Dismantle.
