Reilauto Train Horn Kit for Truck - 178dB 4-Trumpet Air Horn with 12V 150 PSI Compressor & 6L Tank, Weather-Resistant

The Reilauto Train Horn Kit is a complete, high-volume 178dB horn system with four trumpets, a 12V 150 PSI compressor and a 6L (1.6 gal) air tank for trucks, pickups, semis, cars and boats.

Built to deliver an attention-grabbing signal, this kit pairs oversized trumpets with a durable electric compressor and a compact air reservoir so you get a loud, consistent blast without complex plumbing. All components are weather-resistant and supplied with wiring, mounting hardware and a user guide so you can fit the system yourself or hand it to an installer. The kit focuses on sound output, durability and straightforward installation for road, work and marine applications.

How loud is the horn and where will it carry?

The four-trumpet assembly produces up to 178dB at the source, designed for long-distance audibility and strong penetration through traffic and outdoor noise. This places it well above typical vehicle horns and most aftermarket air horns, making it suitable for vehicles that need unmistakable signaling.

• Peak sound rating: 178dB output for maximum presence.
• Four tuned trumpets for full, layered tone and projection.
• Effective in open roads, industrial sites, marinas and busy highways.

What does the compressor and tank deliver for performance?

The included 12V compressor works with a 6L (1.6-gallon) tank to supply stable air pressure for repeatable blasts. The compressor is built for heavy use, includes a built-in filter and features an automatic cut-out to stop pumping above about 115 PSI for safety and longevity.

• Compressor rating: 12V, rated to 150 PSI for quick fill and reliable output.
• Air tank capacity: 6 liters (1.6 gallons) for multiple horn cycles between fills.
• Safety features: integrated filter and automatic shut-off to protect the unit.

Is it weatherproof and durable enough for daily use?

The horn components are constructed from corrosion-resistant materials and sealed to resist rain, fog and temperature swings. That makes the kit suitable for trucks, pickups and boats that operate in harsh conditions or year-round exposure.

• Water-resistant trumpets and compressor housing for outdoor durability.
• Stable frequency output designed to stay consistent over time.
• Heavy-duty mounting hardware and shock pads to reduce vibration wear.

How easy is installation and what’s included?

This package is intended as a one-stop kit with everything needed for mounting and wiring, so many users complete the job quickly without specialized tools. The kit ships with wiring, fuse, mounting brackets, shock-absorbing pads and a clear instruction manual; a caution notes the tank orientation—do not install it upside down.

• Complete accessories: 16.4 ft wiring, fuse, pads and mounting brackets.
• Manual included: step-by-step guide for straightforward setup.
• Typical install time: about 10 minutes for experienced DIYers, longer for first-timers.

Who is this for: The Reilauto Train Horn Kit targets vehicle owners who need unmistakable, long-range signaling — including truck and semi drivers, pickup owners who want a stronger horn, marine users needing audible alerts, and fleet vehicles that operate in noisy environments. It’s also a fit for DIY installers who prefer an all-in-one solution with robust hardware and an automatic compressor safety feature. If you need a high-decibel, weather-resistant horn system with a quick installation path, this kit provides the components and durability to meet those needs.
