FARBIN 4-Trumpet Air Horn Kit for Trucks — 178 dB, 3L Tank & 12V Compressor

FARBIN's 4-trumpet air horn kit is a heavy-duty vehicle warning system that delivers up to 178 dB of multi-tone sound using four zinc-alloy trumpets, a 3L air tank, and a 12V maintenance-free compressor.

Designed for trucks, SUVs, boats and any vehicle needing an unmistakable audible alert, this kit combines a robust compressor, a corrosion-resistant four-horn assembly and a compact air tank. The components are built from durable materials to resist weather and temperature extremes, and the system includes the hoses, mounting hardware, fuse and simple instructions needed for installation.

How loud is this horn and how far will it carry?

The four-trumpet configuration produces up to 178 decibels of sound, creating a layered, attention-grabbing tone that travels farther than single-horn systems. It uses synchronized trumpets to produce a complex waveform that cuts through ambient noise so other road users notice you quickly.

• Peak output: rated at 178 dB across combined trumpets.
• Multi-tone design improves audibility in traffic and open areas.
• Sufficient range to be heard at highway distances and across large lots.

What components are included and what are they made of?

The kit includes four zinc-alloy trumpets, a 3L (0.8 gallon) air tank, a 12V heavy-duty compressor with integrated air filter, mounting brackets, hose, wiring, a fuse and installation instructions. Zinc-alloy trumpet construction offers strength and corrosion resistance for long outdoor service life.

• Four polished zinc-alloy trumpets for durable, stable frequencies.
• 3L air reservoir sized for repeated blasts without long pump times.
• Maintenance-free 12V compressor with automatic safety shutoff at 100 PSI.
• Complete hardware, tubing and electrical fuse for plug-and-play setup.

How easy is installation and what electrical/load requirements are there?

Installation is intended for do-it-yourself or professional fitment and comes with step-by-step instructions and all necessary attachments. The compressor runs from a standard 12V DC vehicle supply and includes a built-in auto-stop feature when internal pressure reaches 100 PSI to protect the unit.

• 12V power requirement; suitable for common truck and car electrical systems.
• Comes with pre-cut hoses, mount brackets and wiring harness for fast assembly.
• Automatic compressor safety prevents over-pressurization of the tank.

What maintenance or safety considerations should I know about?

Regularly inspect fittings, hoses and electrical connections for corrosion or wear, and keep the compressor area free of debris. Because this system reaches high decibel levels, use it responsibly and in accordance with local regulations to avoid startling pedestrians or causing hearing damage.

• Check hose clamps and mounting bolts periodically for tightness.
• Avoid prolonged blasts in enclosed spaces to reduce hearing risk.
• Follow local laws governing use of aftermarket horns on public roads.

Who this is for: The FARBIN 4-trumpet air horn kit suits drivers who need a durable, high-output warning system—commercial truck operators, off-road enthusiasts, boat owners and fleet managers who want a reliable, easy-to-install horn with long-term weather resistance. If you need a loud, multi-tone audible alert with a compact air tank and maintenance-free compressor, this kit provides the hardware and durability expected for heavy-duty use.
