FARBIN Train Horn for Truck 150 dB Snail Air Horn Kit with Integrated Compressor and Relay Harness

The FARBIN Train Horn for Truck is a 150 dB snail-style air horn kit with an integrated compressor and relay harness that delivers an attention-grabbing, vehicle-mounted warning sound without requiring an external air tank.

Designed for cars, trucks, SUVs, RVs, boats and off-road vehicles, this FARBIN horn combines high volume output, durable construction and a plug-and-play wiring harness so you can install a powerful signaling system quickly. The kit includes an upgraded onboard compressor, red copper coil components and chrome-plated trumpet housings that withstand typical road temperatures and weather exposure. It’s built to be loud, reliable and compatible with any 12V electrical system.

How loud is the FARBIN Train Horn and where will you notice it?

This horn produces roughly 150 dB at full power, matching levels commonly found in train-style horns used for maximum roadway presence. That intensity makes it effective at drawing attention in traffic, on highways, and in noisy environments, while the snail trumpet design gives the sound a full, directional tone.

• Peak sound level: approximately 150 dB for high audibility
• Snail-style trumpets project sound forward for directional warning
• Useful on busy roads, work sites, marinas and remote trails

What components come with the kit and how does the onboard compressor work?

The kit includes the snail-style trumpets, an upgraded compressor (with red copper coil and vacuum chrome plating), a relay harness and all necessary mounting hardware. The built-in compressor pressurizes the trumpets on demand, so no separate air tank is required; the relay harness simplifies electrical connection to a 12V source and a push button or switch.

• Integrated compressor: supplies air instantly, no external tank needed
• Relay harness: color-coded wiring and diagrams for straightforward installation
• Durable materials: chrome plating and quality coils for longer service life

How difficult is installation and what vehicles are compatible?

Installation is intended to be user-friendly: the package contains a wiring harness, color wiring diagram and mounting hardware so most owners with basic tools can complete the job. Because the horn runs on 12V, it is compatible with the majority of cars, trucks, SUVs, RVs, motorcycles and marine craft.

• Wiring guide included with color diagrams for easier setup
• Standard 12V compatibility: fits most road and off-road vehicles
• Mounting hardware provided for common installation locations

What are the durability and environmental features of this horn kit?

FARBIN designed this horn with longevity in mind: chrome-plated trumpets resist corrosion and the compressor’s copper coil improves heat tolerance and responsiveness. It is intended to function across a range of temperatures and driving conditions, making it suitable for year-round use in varied climates.

• Chrome-plated exterior for corrosion resistance
• Red copper coil in compressor for faster response and heat resilience
• Built for regular use on roads, work environments and marine conditions

Who is this for? Drivers and fleet operators who need a powerful, self-contained audible warning system will benefit from the FARBIN Train Horn for Truck. It’s aimed at vehicle owners who want a louder, more authoritative horn for safety and presence—particularly those who operate in noisy settings, motor enthusiasts wanting a distinct sound, and anyone seeking a kit that installs without adding a separate air tank. Always check local laws and regulations about aftermarket horns and use them responsibly.
