VEVOR 4-Trumpet Air Horn Kit for Trucks, Black — 150dB 12V with 0.8‑gal Tank

VEVOR 4 Trumpet Air Horn Kit is a complete 12V train-horn system that produces up to 150dB using four chrome-plated trumpets, a 0.8-gallon tank, and an automatic 90–120 psi compressor for powerful, reliable alerts.

This kit combines a heavy-duty compressor, welded air tank, solenoid valve, and four tuned trumpets to deliver loud, penetrating sound for pickup trucks, SUVs, and other 12V vehicles. It’s engineered for durable outdoor use with anti-rust finishes, thermal protections, and vibration damping to keep the unit working in varied conditions.

How loud is this horn and when will I notice the difference?

The system is rated up to 150dB, giving a strong, far-reaching tone designed to cut through traffic noise, wind, and rain. That makes it effective for gaining attention on highways, in rural areas, or when visibility is reduced.

• Peak output approximately 150dB for long-distance audibility
• Four trumpets create a layered, train-like chord for better recognition
• Useful in heavy traffic, adverse weather, or remote roads

What components are included and how do they work together?

The kit ships complete with four trumpets, an electric compressor, a 0.8-gallon welded tank, a solenoid valve, piping, and mounting hardware. The compressor fills the tank between 90 and 120 psi, the solenoid opens to feed air to the trumpets, and the trumpets produce the audible signal.

• Compressor with automatic on/off between 90–120 psi and protective fuses
• 0.8-gallon welded tank with drain plug to remove accumulated water
• Solenoid valve and piping for reliable air delivery to the trumpets

How durable is the kit for outdoor and road use?

VEVOR constructed the horns and fittings from zinc alloy and treated steel to resist corrosion and impacts. The compressor includes thermal overload protection and the kit features rubber cushions to reduce vibration and extend life when mounted under a vehicle.

• Anti-rust coating on metal parts for long-term outdoor exposure
• Thick rubber cushion for shock absorption and quieter mounting
• Motor temperature control and high-temp pipe rated to 120℃

Is this installation compatible with my vehicle’s electrical system?

The horn kit is built for 12V DC systems and works with most trucks, SUVs, and similar vehicles that use a 12V battery. Wiring requires a separate switch and cord (not included), and basic electrical know-how or professional installation is recommended for optimal performance and safety.

• Designed for standard 12V vehicle battery systems
• Power switch and cord must be supplied separately for installation
• Simple wiring layout but professional install recommended for clean routing

Who is this for: Drivers who need a high-decibel, durable horn solution—commercial drivers, off-road enthusiasts, rural commuters, and anyone wanting a clear, train-style alert for better roadside presence. The VEVOR kit suits owners comfortable with vehicle modifications or who can have the system fitted by a mechanic, offering robust materials and automatic compressor control for reliable everyday use.
