FARBIN Train Horns 12V Dual-Tone Air Horn with Cover — Built-In Pump, Relay Harness

FARBIN Train Horns is a compact 12V air horn kit that delivers a powerful dual-tone blast for cars, motorcycles and other vehicles while including an integrated pump, wiring harness and protective cover.

Designed to combine bold sound with a streamlined look, this horn set blends aerodynamic styling with robust components so you can add a high-decibel alert without large external tanks or elaborate installation. The kit ships with mounting hardware, relay and fuse so it’s ready to wire into most 12V systems. Built for repeated use and wide temperature ranges, the system aims to provide a reliable, attention-getting signal on the road or water.

How loud is the FARBIN Train Horn and where will it be heard?

The horn produces an extremely loud dual-tone output designed to be noticed by drivers and pedestrians. Measured from a short distance in testing conditions, the system can reach high decibel levels suitable for heavy-traffic or noisy environments. Use responsibly and in accordance with local laws about vehicle noise.

• Dual high/low tone for a fuller, attention-grabbing signal
• Produces very high decibel output from its compact trumpet configuration
• Audible at distance in urban and highway settings when installed correctly

What hardware and components are included for installation?

The kit arrives with the integrated electric horn assembly, a protective cover, mounting screws, a relay-equipped wiring harness and a fuse so you can connect to a 12V power source without sourcing extra parts. The compact design fits many mounting points on motorcycles, cars, trucks, boats and utility vehicles. Basic hand tools and a few minutes of wiring are usually all that’s needed for a secure fit.

• 12V electric double-tone horn with built-in pump — no separate air tank required
• Relay harness and inline fuse for safe, reliable power routing
• Mounting screws and a shaped cover for streamlined protection and appearance

How durable is the pump and electrical system under real-world conditions?

The internal pump uses reinforced copper windings and improved motor terminals to increase lifespan and tolerate a wide temperature range. It’s built to operate through many cycles without an external air source, offering consistent blasts over time. The components are specified to resist harsh conditions encountered on road and watercraft applications.

• Thickened copper coil and upgraded wire terminals for extended durability
• Rated to operate across extreme temperatures from cold to high heat
• Designed for high cycle life to support frequent use without an external compressor

Will this horn fit my vehicle and how compact is the design?

The horn is engineered for broad 12V compatibility, making it a suitable replacement or supplemental alert on cars, motorcycles, trucks, buses, vans, boats and golf carts. Its reduced footprint allows installation in tight engine bays, under seats or behind trim panels where space is limited. Check mounting clearances and wiring route before installation.

• Compatible with most 12V vehicles and power systems
• Small, aerodynamic trumpet housing fits most mounting locations
• Installation-friendly harness lets you connect to battery or existing horn circuit
