4 Trumpet Train Horns Kit 150dB 12V Truck Air Horn

Hear the power with the 4 Trumpet Train Horns Kit 150dB 12V for trucks. This comprehensive air horn kit includes four horns, a solenoid valve, a 0.8-gallon air tank, a compressor, and air pipes, delivering an immediate, reliable horn response thanks to an auto-inflating compressor. Built with rust-proof materials, it’s designed to perform safely in any weather, reliably alerting cars, pedestrians, and animals on the road.

Delivering a powerful 150 dB wake-up call, this kit is ideal for long-distance driving and challenging conditions. The rugged construction uses heavy-duty zinc alloy and steel with an anti-rust coating to resist corrosion, impact, and wear. The available air system maintains optimal pressure: the compressor automatically inflates when tank pressure drops below 90 psi and pauses at 120 psi to prevent overpressure, while a sensitive pressure gauge keeps the operator informed. A leak-proof design and tightly welded tank minimize risk of loss, ensuring every horn blast lands where it needs to.

Designed for universal 12V compatibility, this kit integrates with standard 12V electrical systems across a wide range of vehicles. The PA pipe withstands temperatures up to 120℃, and the motor’s 100℃ temperature control switch protects the system from overheating. Fuses safeguard the compressor, and a tank drainage plug makes it easy to release accumulated water. Thick, shock-absorbing rubber pads can be installed between the air tank’s bottom bracket and the vehicle to reduce movement and noise during travel. Note: Power switch and power cord are not included.
