FARBIN 12V Air Horn for Cars & Motorcycles — Double-Tone 150 dB, Compact Weather-Resistant Kit

FARBIN Air Horn is a compact 12V train-style horn kit that delivers up to 150 dB of warning sound for cars, motorcycles, trucks and boats while requiring no external air source.

Designed for drivers who need a powerful, weather-resistant audible signal in a small footprint, this FARBIN horn kit combines an aerodynamic, decorative shell with a high-performance integrated air pump and a simple wiring harness. It replaces or supplements factory horns on most 12V vehicles and is built to withstand wide temperature ranges and heavy use. The package includes mounting hardware, a relay harness and a fuse to make installation straightforward for DIYers and professional installers alike.

How loud is the FARBIN Air Horn and where will I notice it?

The horn produces a peak sound level tested at approximately 150 dB measured 2 meters in front of the device, designed to cut through traffic noise and alert drivers and pedestrians. It combines high and low tones for a fuller, attention-grabbing signal.

• Measured output: ~150 dB at 2 m (per test standard)
• Dual-tone design for broader frequency coverage
• Effective in urban, highway and off-road environments
• Suitable for motorcycles, cars, trucks, vans, boats, golf carts

What makes the pump and motor more durable than typical horns?

FARBIN upgraded the air pump with a thickened copper coil and reinforced copper wire terminals to withstand repeated cycling and extreme temperatures. The motor and pump are specified to tolerate prolonged use and harsh environmental conditions without an external air source.

• Thickened red copper coil for improved conductivity and heat tolerance
• Rated for -60°C to 100°C operating temperatures
• Tested for over 100,000 consecutive actuations
• No separate air compressor required — fully integrated unit

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

The FARBIN horn comes as a ready-to-install kit with the double-tone horn, mounting screws, relay wiring harness and a fuse, so no extra accessories are normally needed. The compact design allows mounting in tight engine bays or under fenders with standard tools.

• Included: integrated high/low horn, fixing screws, relay harness, fuse
• 12V electrical compatibility for most vehicles
• Compact size fits many mounting points, minimal modification
• Wiring harness simplifies connection to vehicle power and switch

Will this horn fit my vehicle and how will it affect style?

The streamlined, aerodynamic shell was designed to blend with vehicle bodywork rather than appear intrusive, so it works as both a functional upgrade and a visual accent. It’s compatible with a wide range of 12V platforms, making it a practical replacement or an additional warning device.

• Compatible with any 12V vehicle: cars, motorcycles, trucks, buses, boats
• Compact footprint enables flexible mounting options
• Aerodynamic casing doubles as a decorative accent
• Works as a direct replacement or supplementary horn

Who this is for: drivers, riders and fleet operators who want a high-volume, durable horn that’s simple to install and engineered for heavy-duty use. If you need a loud, weather-resistant audible warning without adding an external air compressor, and you prefer a horn that integrates cleanly with vehicle styling, the FARBIN Air Horn kit offers a practical, long-lasting solution.
