FARBIN 12V Dual Trumpet Air Horn Kit with 2 Compressors — 178dB Train-Style Long-Range

This complete FARBIN kit includes two tuned trumpet tubes, a pair of upgraded compressors, a heavy-duty wiring harness, mounting bracket and relay so you can install a high-decibel air horn on any 12V vehicle. The trumpets are longer for extended sound projection, while thickened copper coils and reinforced wiring increase reliability in extreme temperatures. The set is designed for straightforward bolt-on installation and works with trucks, buses, jeeps, boats and other 12V systems.

How loud and far does this horn reach?

The paired trumpets and dual compressors produce a combined peak output rated at about 178dB, designed to cut through traffic and busy environments. The longer trumpet lengths improve propagation so the tone carries farther than short, compact horns.

• 178dB peak sound level for strong attention-getting blasts
• Extended trumpet tubes (370mm and 410mm) for better range
• Dual compressors sustain pressure for longer single-tone durations

What makes the compressors and wiring more durable?

FARBIN upgraded both compressors with thicker red-copper coils to improve heat tolerance and reliability across a wider temperature range (-30°C to 80°C). The wiring harness uses enlarged copper conductors and a higher-threshold fuse to reduce voltage drop and protect the circuit under heavy load.

• Two high-power compressors with reinforced copper coils
• Operable in extreme temperatures from -30°C to 80°C
• Thickened wiring harness and improved fuse protection for safer operation

How easy is installation and what’s included?

The kit ships with all mounting hardware, a relay, nut set and a labeled wiring harness so you can complete installation yourself in most cases. No specialty tools or professional mechanic are required for the basic install; many users can finish assembly in around 10 minutes.

• Complete accessories: relay, wiring harness, brackets and nuts
• Step-by-step instructions for straightforward bolt-up installation
• Designed for standard 12V vehicle electrical systems

Will this horn work on my vehicle type?

Yes — the FARBIN train horn kit is compatible with any 12V system, making it suitable for trucks, pickups, buses, vans, SUVs, jeeps, boats and yachts. It’s intended to improve audibility in heavy traffic, work sites or emergency scenarios where a louder warning signal is needed.

• Fits most 12V vehicles: truck, van, pickup, car, boat, jeep and bus
• Bracket and hardware designed for flexible mounting locations
• Useful for large vehicles and situations requiring high audibility
