FARBIN 12V Air Horn for Trucks & Cars — Compact 150 dB Electric Train-Style Horn with Wiring Harness (Black)

FARBIN's 12V air horn delivers an instant, compact 150 dB alert for any 12-volt vehicle, with an upgraded electric compressor and an included wiring harness for straightforward installation.

This air horn kit combines a powerful multi-tone trumpet with a built-in electric pump so you don't need a separate onboard air source. Engineered to operate across a wide temperature range and built from corrosion-resistant parts, the kit suits trucks, cars, SUVs, RVs, boats and other 12V vehicles that need a loud, reliable audible warning. The package includes clear wiring diagrams and plug-and-play connectors to simplify fitting on most vehicles.

How loud is the FARBIN air horn and where is that noise level useful?

The horn produces up to 150 dB peak sound pressure, enough to be heard clearly in heavy traffic, construction sites, and on highways. It’s designed to cut through ambient noise for improved audibility without relying on vehicle engine air systems.

• Rated peak output: 150 dB for strong attention-getting sound.
• Multi-chime trumpet design for distinct, far-reaching tones.
• Suitable for noisy environments like industrial sites and busy roads.

What does the upgraded compressor add and how does it perform?

The horn uses an upgraded electric pump with a copper coil and vacuum chrome plating for faster response and longer life. Because the pump is integrated, you can mount the horn even when an external air tank is not present.

• Electric compressor provides immediate air pressure on demand.
• Red copper coil and plated components resist corrosion and heat.
• Operates reliably across -30°C to +80°C for varied climates.

How easy is installation and what’s included in the wiring kit?

FARBIN supplies a full wiring harness and color-coded diagrams so most users can install the horn with basic tools. The harness includes connectors, relays and mounting hardware to help ensure a safe, tidy electrical fit on 12V systems.

• Complete wiring harness with relay and fuse for safe operation.
• Color-coded diagram and step-by-step wiring instructions included.
• Mounting brackets and hardware for flexible placement options.

Will this horn fit my vehicle type and what environments can it handle?

The unit is built for general 12V compatibility and fits most trucks, cars, SUVs, RVs, motorcycles and marine craft with a 12V electrical system. Tough materials and temperature-tolerant design let it perform in harsh weather and off-road conditions.

• Designed for any vehicle with a 12V electrical system.
• Durable construction for off-road, marine, and heavy-duty use.
• Compact footprint allows mounting in tight engine bays or behind bumpers.

Who this is for: drivers and fleet operators who need a compact, high-volume audible warning without adding an external air tank — including truckers, delivery drivers, off-road enthusiasts, RV owners and boaters wanting clearer, more reliable signaling. Installers who value a bundled harness and clear instructions will also appreciate the reduced installation time. If you need a rugged, high-output horn that fits common 12V systems and withstands extreme temperatures, this FARBIN kit is built for that use.
