Competition Series 3 Trumpet Train Horn - Super Loud 150 dB

In this review the United Pacific Competition Series 3 Trumpet Train Horn is evaluated for drivers and truck enthusiasts who want an imposing, durable air horn with simple installation. The bottom line: this single-bracket 3-trumpet horn delivers a very loud, freight-train style blast and is built for heavy use, making it a solid choice for big rigs and custom trucks that need maximum attention-grabbing sound. It is best chosen when raw volume and rugged construction are the priorities rather than subtlety.

Key Features

• Three trumpet design: All three horns are mounted on one solid bracket for compact attachment and consistent sound staging across the set.
• Heavy-duty solenoid included: The 12-volt electric air solenoid is supplied with the horn so the electrical activation is ready out of the box.
• High maximum pressure: Rated to handle up to 150 PSI max, allowing for very powerful sound output when paired with an appropriate compressor and tank.
• Durable construction: Thicker, larger trumpet pieces than earlier models are intended to improve longevity and sustain louder output over time.
• Complete mounting hardware: Mounting pad and bolts are included to simplify installation and reduce the need for additional parts.
• Chrome finish: The chrome look provides a classic, high-visibility appearance on trucks and custom vehicles.

Who It's For

This horn is aimed at big rig drivers, truck owners, and vehicle modifiers who need an extremely loud signaling device and value a strong, durable build. It suits those who already have or will install a compatible compressor and air tank to reach the 150 PSI capability.

It is less suitable for drivers who need a subtle or neighborhood-friendly horn, or for those seeking a full factory-style installation without aftermarket modifications. Anyone concerned about very high decibel levels or legal limits in dense urban areas should consider a lower volume alternative.

Pros & Cons

Pros

• Very loud output provides unmistakable audible presence for safety or signaling.
• Sturdy single-bracket build simplifies mounting and keeps the three horns aligned.

• Chrome finish and robust materials give a quality look and feel valued by customers.

Cons

• Extremely high volume may be too loud for some environments and can limit where it is appropriate to use.
• A few customers reported occasional functionality issues, so individual units may require troubleshooting.
