HK 150dB Super Loud Dual Trumpet Air Horn Kit is a 12V compressor-driven signaling system that delivers an attention-grabbing horn tone designed for vehicles, trucks, trains, and boats.

This all-metal air horn kit combines two chrome-plated zinc trumpets with an upgraded compressor and all-copper coil to produce a powerful, weather-resistant sound. Built to mount on most 12V vehicles, the HK kit aims to improve on-road presence and audible warning capability while offering durable materials and straightforward installation hardware.

How loud is the HK 150dB dual trumpet air horn?

The horn is engineered to reach up to 150 decibels at source under ideal conditions, producing a strong, clear tone intended to cut through road and environmental noise. Decibel output varies with mounting location, distance, and surrounding surfaces.

  • Maximum rated output: up to 150 dB (subject to real-world variation)
  • Two trumpet design for fuller tonal projection
  • Chrome-plated metal trumpets for consistent tone quality

What components come with the kit and how durable are they?

The kit includes dual chrome-plated zinc trumpets, an upgraded compressor with an all-copper coil, mounting brackets, and wiring for 12V systems. Materials are selected for corrosion resistance and long-term use in exposed vehicle environments.

  • Chrome-plated zinc alloy trumpets resist rust and maintain tone
  • All-copper coil in the compressor for reliable electrical performance
  • Universal mounting bracket and hardware for versatile installs

Which vehicles and power systems are compatible with this air horn?

The HK horn is designed for 12-volt DC systems, making it compatible with most cars, trucks, SUVs, motorcycles, buses, yachts, and off-road vehicles. Installation location and wiring should follow local regulations and vehicle-specific clearance requirements.

  • Works with standard 12V DC vehicle electrical systems
  • Suitable for cars, trucks, boats, motorcycles, buses, and off-road rigs
  • Includes universal mount for flexible placement options

How easy is installation and what support is available?

Installation is intended to be straightforward using the included universal bracket, wiring, and hardware, but wire routing and mounting will depend on vehicle type. HK supports the product with a 30-day money-back offer, 1-year warranty, and lifetime technical assistance for troubleshooting.

  • Universal mounting hardware included for most installs
  • Basic 12V wiring required; professional installation recommended when unsure
  • 30-day return, 1-year warranty, and lifetime technical support from HK

Who is this for: Drivers and operators who need a robust, high-volume signaling solution for larger vehicles or noisy environments — including truckers, boat owners, off-road enthusiasts, and fleet managers — will find the HK 150dB dual trumpet air horn suitable. If you want clear, durable auditory presence from a metal trumpet and compressor assembly with 12V compatibility and backed support, this kit is built for those needs. Follow local sound regulations and safety guidance when installing and using the horn.
