FARBIN 12V Air Horn for Trucks & Cars — Compact 150 dB Train Horn Kit, Black with Wiring Harness

FARBIN's 12V electric air horn is a compact, 150 dB super‑loud train-style horn kit designed to fit trucks, cars, SUVs, boats and any 12V vehicle for instant, attention‑getting warning sound.

This plug-and-play horn kit pairs a high-output compressor with dual trumpet horns and a full wiring harness so you can add a powerful signaling device without an onboard air tank. Built from weather-resistant materials and an upgraded red-copper coil compressor, the unit works across wide temperatures and was designed to be straightforward to mount and wire on most 12V vehicles.

How loud is this horn and when is that level useful?

The FARBIN horn produces up to 150 dB, a sound level intended to cut through traffic noise and long-distance environments. It’s suited for situations where a standard car horn might not be noticed, such as on highways, in convoys, around large commercial vehicles, or on watercraft.

• Peak output: up to 150 dB for clear audible range.
• Dual trumpet design for broader directional reach.
• Effective in noisy, open, or long-distance scenarios.

What makes installation and wiring simple for a DIYer?

The kit includes a pre-wired harness and color-coded wiring diagram so you can connect the horn, compressor, and switch without fabricating connectors. The compact compressor eliminates the need for a separate air tank, reducing mounting complexity and installation time.

• Complete wiring harness with color-coded instructions included.
• No separate air source required thanks to the upgraded compressor.
• Mounting brackets and compact profile fit varied vehicle layouts.

Is the horn durable enough for harsh weather and heavy use?

FARBIN designed the unit from weather-resistant components and an upgraded compressor to operate across wide temperature ranges, making it suitable for seasonal and all-weather use. Corrosion-resistant finishes and quality materials help maintain performance over time.

• Operates from -30°C to +80°C for wide climate tolerance.
• Red copper coil and vacuum chrome plating on critical parts for longevity.
• Rugged housing and hardware resist road and marine environments.

Which vehicles can use this 12V air horn?

Any vehicle with a 12V electrical system can support the horn: passenger cars, trucks, SUVs, RVs, boats and motorcycles. The universal wiring harness and compact compressor let it be adapted to a broad range of installations without vehicle-specific parts.

• Fits 12V cars, trucks, SUVs, vans, RVs, boats and motorcycles.
• Works with standard 12V battery and fuse-protected circuits.
• Suits both under-body and engine-bay mounting locations.

Who this is for: drivers and fleet operators who need a reliable, high-output signaling device—especially those working in noisy environments, towing or hauling, navigating busy highways, or operating recreational boats. If you want a compact, easy-to-install horn that delivers a train-style blast without adding an air tank, this FARBIN 12V 150 dB kit offers a practical, durable option.
