FARBIN Electric Air Horn for Truck — Compact 150 dB Train-Style Horn Kit, 12V with Built-In Compressor and Buttons

This electric air horn by FARBIN combines a small footprint with high output so drivers can add a train-like warning tone without requiring an external air tank. Built with durable materials and a redesigned compressor, the kit operates from a standard 12V vehicle system and mounts in tight engine bays or underbody locations. The package includes an accessible wiring harness and buttons so both professional installers and hands-on owners can complete the fitment.

How loud is this horn and what does that volume mean on the road?

The horn produces up to 150 dB, which puts it in the upper range of vehicle warning devices and ensures it can be heard over traffic and heavy equipment. That high sound output is intended for conspicuous alerting in noisy environments rather than casual signaling.

• Peak sound level: approximately 150 dB
• Designed for visibility and audibility in busy or industrial settings
• Not intended for continuous use—short bursts are recommended

What components are included and how does the upgraded compressor help?

The kit comes with a compact electric compressor, horn trumpet(s), mounting hardware, wiring harness and control buttons. The upgraded pump features a red copper coil and vacuum chrome plating for faster response and improved resistance to heat and corrosion.

• Self-contained compressor—no separate air tank required
• Durable materials that tolerate -30℃ to +80℃ operating ranges
• Wiring harness with color-coded diagrams for straightforward connection

How easy is installation and what vehicles are compatible?

Installation is straightforward for anyone comfortable with basic vehicle wiring or mounting. The kit supports any 12V system, making it compatible with trucks, cars, vans, SUVs, RVs, boats and many off-road vehicles.

• Includes harness and labeled wiring instructions
• Compact form factor fits in tight engine bays or under-tray locations
• Suitable for most 12V vehicles—trucks, cars, motorcycles, RVs and boats

What durability and operating conditions can I expect?

FARBIN designed the horn with weather and temperature resistance in mind so it performs reliably across a wide range of climates. Corrosion-resistant finishes and quality components help extend service life even when mounted externally.

• Working temperature range: -30℃ to +80℃
• Vacuum chrome-plated parts for added corrosion resistance
• Robust build for automotive and marine environments

Who is this for? The FARBIN compact electric train horn is aimed at drivers who need an unmistakable warning device—commercial vehicle operators, worksite and farm vehicle owners, boaters navigating busy marinas, and off-road enthusiasts who require superior audibility. It is best for those who want an easy-to-install, high-volume horn that fits 12V systems and performs reliably in extreme temperatures. If you need a loud, compact horn with a self-contained compressor and clear installation guidance, this kit offers a pragmatic upgrade to your vehicle’s signaling capability.
