FARBIN Air Horn — Compact 12V Chrome Train Horn, 150 dB Three-Trumpet with Built-In Compressor

FARBIN Air Horn is a compact, electric 12V train-style horn kit that delivers up to 150 dB of sound using an onboard compressor for instant, powerful alerts.

This kit combines a compact three-trumpet chrome horn, an upgraded electric compressor, wiring harness and mounting hardware so you can add a pronounced, attention-grabbing horn to trucks, cars, SUVs, RVs and boats without an external air tank. The compressor’s copper coil and vacuum chrome finish improve responsiveness and durability, while the included relay and color-coded wiring simplify installation for most 12V vehicles.

How loud is this horn and will it be heard in traffic?

The FARBIN horn is rated at 150 dB at source, producing a train-style tone designed to cut through ambient noise. In real-world driving this makes it easily noticeable in busy streets, on highways, and in noisy industrial or off-road environments.

• Peak sound output: up to 150 dB
• Three-trumpet train tone for broader sound dispersion
• Engineered to project over traffic and wind noise

What does the kit include and how does the built-in compressor work?

The package contains the chrome trumpet set, an upgraded electric air compressor with red copper coil, a mounting bracket, relay, fuse and a full wiring harness with color diagrams. The compressor supplies air on demand, so you don’t need a separate air tank or external air source.

• 12V electric compressor with fast-response valve
• Pre-wired harness and color-coded instructions for easier hookup
• Mounting hardware and relay for safe electrical integration

How hard is installation and will it fit my vehicle?

Installation is designed for do-it-yourself mechanics and professional installers. The harness and clear wiring diagrams reduce guesswork; most 12V passenger vehicles, trucks, RVs and boats accept the kit with basic mounting and electrical work.

• Works with 12V electrical systems common in cars, trucks, RVs and boats
• Includes relay and fuse to protect vehicle circuits
• Hand tools and basic wiring skills typically required

Is this durable enough for outdoor and varied temperature use?

Materials and finish are selected for resilience: vacuum chrome plating on the compressor and corrosion-resistant trumpet surfaces help withstand wet or hot conditions. The upgraded internal components aim to maintain reliable operation across typical automotive temperature ranges.

• Vacuum chrome plating for corrosion resistance
• Red copper coil for improved thermal and electrical performance
• Built to tolerate typical automotive temperature variations

Who is this for: The FARBIN Air Horn is aimed at drivers who need a loud, unmistakable warning tone—professional drivers, off-road enthusiasts, RV owners, boat operators and anyone wanting a high-output horn upgrade without installing an air tank. It’s especially useful when you need a compact, self-contained kit that installs on standard 12V systems and projects clear, train-style sound for safety and visibility on roads, trails and waterways.
