Deliver 150dB of penetrating train-horn sound with this four-trumpet air horn kit for your vehicle.
You get four air trumpets, a solenoid valve, a 0.8-gallon tank, a compressor, and pipes, plus screws, bolts, fuses, and a detailed instruction manual for complete assembly.
The 90–120 psi compressor auto-inflates when pressure falls below 90 psi and stops at 120 psi to prevent overpressure, with a sensitive gauge for real-time monitoring.
Heavy‑duty construction uses zinc alloy and steel with anti‑rust coating; the air tank is tightly welded to minimize leaks and a drainage plug simplifies water removal.
Designed for any 12V system; PA pipe withstands up to 120°C and the motor includes a 100°C temperature control switch for protection; thick rubber pads dampen vibration and reduce road noise. Note: power switch and power cord not included.
