FARBIN 4-Trumpet Air Horn Kit 178 dB — 3L Tank, 12V Compressor for Trucks & SUVs

FARBIN's 4-trumpet air horn kit delivers an extremely loud 178 dB alert using four zinc-alloy trumpets, a 3L air tank and a 12V maintenance-free compressor for reliable vehicle signaling.

This complete train-style horn set is built for drivers who need a powerful, attention-grabbing warning system. The assembly combines a heavy-duty zinc alloy horn assembly, a 0.8-gallon (3L) air reservoir and an integrated 12V compressor with automatic pressure cut-off. Everything required for installation — hose, fittings, mounting brackets, fuse and instructions — is included so you can fit the system to trucks, SUVs or other large vehicles without specialist tools.

How loud is the FARBIN 4-trumpet system and when will I hear it?

The horn produces up to 178 decibels with four trumpets sounding together, designed to carry over long distances and through noisy environments. While extremely loud, correct use is important because such volume can startle nearby pedestrians or animals.

• Peak output: up to 178 dB when all horns operate simultaneously
• Four tuned trumpets for a full, far-reaching tone
• Audible range suitable for highways, construction zones and marine settings

What components come in the kit and how durable are they?

The set is delivered as a complete kit: four zinc-alloy trumpets, a pre-charged 3L air tank, a 12V heavy-duty compressor with integrated filter, braided air hose, wiring, mounting hardware and a fuse. The materials and finish are chosen to resist weather and everyday road wear so the kit remains functional in demanding conditions.

• Zinc alloy trumpets for corrosion resistance and long service life
• 3L (0.8 gallon) tank sized for multiple blasts between pump cycles
• Compressor with automatic shutoff and built-in filter for maintenance-free use

Is installation difficult and what safety features are included?

Installation is intended for do-it-yourselfers with basic hand tools; the package includes clear instructions and all necessary fasteners and hose fittings. The compressor features an automatic safety cut-off to stop pumping at the preset pressure, protecting the unit from over-pressurization.

• Complete mounting kit and hose included for straightforward installation
• Compressor automatically stops pumping when internal pressure limit is reached
• Electrical fuse included to safeguard wiring and vehicle circuits

Who is this for? The FARBIN 4-trumpet air horn kit is for drivers who need an unmistakable, long-range signaling device — fleet operators, tow and utility trucks, off-road enthusiasts, or anyone who requires a durable, sale-ready horn system. It’s aimed at users comfortable performing a moderate vehicle installation or who can provide basic shop assistance. Because this horn produces very high sound levels, it’s best suited for professional or industrial contexts where strong audible warnings are necessary.
