VEVOR 4-Trumpet Air Horn Kit 12V — 1.6 gal Tank, 150 dB Compressor & Gauge

VEVOR's 4 trumpet air horn kit is a complete 12V train-horn system that produces 150 dB, driven by a 90–120 psi compressor and a 1.6‑gallon tank for powerful, long-range alerts.

This heavy-duty horn kit gives vehicles a loud, attention-grabbing sound with a compact, weather-resistant design built for trucks, SUVs, vans, boats, and other 12V systems. The package combines four zinc-alloy trumpets, a solenoid valve, air lines, a pressure-regulated compressor, and a welded 1.6-gallon tank so you can install a high-volume alert on virtually any 12V vehicle. Materials and safety features reduce leaks and protect the compressor from overload and heat.

How loud and far can this horn be heard on the road?

The quartet of trumpets produces up to about 150 dB at source, giving the horn strong penetration for long distances and noisy environments. That makes it effective for alerting other drivers, pedestrians, or wildlife in busy or low-visibility conditions.

• Rated peak volume: approximately 150 dB
• Four tuned trumpets for layered sound and distance
• Designed to cut through traffic noise and wind
• Best performance when mounted clear of obstructions

What does the compressor and tank do to ensure consistent performance?

The included air compressor runs between 90 and 120 psi and automatically cycles to maintain pressure, while the welded 1.6-gallon (6 L) tank stores compressed air for immediate discharge. A sensitive pressure gauge shows real-time levels and built-in electrical protections help prevent damage from overloads.

• Compressor automatic cut-in at below 90 psi and cut-out above 120 psi
• 1.6‑gal welded tank for stable air supply and fewer compressor cycles
• Pressure gauge for monitoring; drainage plug for water removal
• Fuses and thermal control protect the motor from overheating

How durable and weatherproof is the VEVOR horn kit?

Components use heavy zinc-alloy trumpets and steel fittings with anti-rust coatings to resist corrosion, impacts, and wear. The compressor and tank are built to limit air loss, and temperature-resistant tubing plus rubber cushions reduce vibration and extend service life in varied climates.

• Zinc-alloy trumpets and coated steel hardware for corrosion resistance
• PA tubing rated to 120℃ for heat resilience
• Thick rubber cushion for noise reduction and shock absorption
• Welded tank and tight compressor seals to minimize leaks

Is this kit easy to fit to my vehicle and what electrical requirements apply?

The horn system is engineered for universal 12V battery systems, so it installs on most cars, trucks, vans, and marine 12V platforms with basic wiring and mounting skills. The kit includes trumpets, air lines, solenoid valve, tank, and compressor; note that a power switch and wiring harness are not included and should be added to complete the installation.

• Compatible with any standard 12V vehicle electrical system
• Includes mounting hardware, solenoid valve, and piping
• Requires user-supplied power switch, wiring, and basic tools
• Recommended to mount trumpets in clear, forward-facing location

Who is this for: The VEVOR 4 Trumpet Air Horn Kit is aimed at drivers who need a high-volume alert system for safety or signaling—commercial truck operators, off-road enthusiasts, boat owners, and anyone wanting a robust, long-range horn for a 12V vehicle. It suits installers who can handle basic electrical wiring and mounting and who want a durable, professional-grade kit with safety protections and weather-resistant materials.
