FARBIN 24V Truck Horn Dual-Tone — Loud Waterproof Train-Style Horn for Trucks & Heavy Equipment, 130 dB

The FARBIN Horns Truck Horn is a 24V dual-tone, train-style loud alarm that delivers up to 130 dB of clear, attention-grabbing sound in a weatherproof package.

Built for heavy vehicles and industrial equipment, this horn pairs a powerful acoustic design with rugged materials to produce a deep, far-reaching blast that improves on-road visibility and safety. Designed specifically for 24V electrical systems, the unit combines a durable ABS housing, a corrosion-resistant mounting bracket, and a waterproof enclosure so it performs reliably in rain, mud, and cold conditions.

How loud is this horn and how far will it be heard?

The FARBIN horn reaches approximately 130 dB at the source, producing a commanding sound profile that cuts through traffic noise. While exact audible range depends on environment and obstructions, the dual-tone pattern is tuned for maximum noticeability in open and urban settings.

• Peak sound pressure: ~130 dB at source.
• Dual-tone output for attention-grabbing modulation.
• Optimized waveform to project sound over long distances.

Will this work on my vehicle and what electrical requirements does it need?

This horn is engineered for 24V systems only — common on trucks, buses, trains, heavy equipment and marine craft. It is not compatible with 12V vehicles unless used with a proper voltage converter or relay system.

• Input: 24V DC power supply required.
• Not suitable for direct 12V installation without conversion.
• Can be wired with standard automotive relays and fuses for safe operation.

How durable is the horn and how does it handle extreme conditions?

Constructed from high-quality ABS with a sealed waterproof shell and an iron mounting bracket, this horn is built to withstand road vibration, moisture, and salt exposure. The corrosion-resistant finish and robust mechanical components are intended for long-term field use.

• Housing: rugged ABS polymer with sealed joints.
• Mounting: heavy-duty iron bracket for stable attachment.
• Weatherproofing: designed to resist rain and spray during operation.

What are the common applications and installation considerations?

Typical fits include commercial trucks, buses, trains, excavators, and ships where a high-volume alert is required. Installation should follow vehicle wiring best practices, using a relay, fuse, and secure ground to protect both the horn and the vehicle electrical system.

• Ideal for commercial and industrial 24V vehicles and equipment.
• Use an appropriate relay and inline fuse for safety and longevity.
• Position where sound projection is unobstructed and grounding is solid.

Who is this product for? Professionals and fleet managers looking for a reliable, high-decibel warning device for 24V trucks, buses, heavy machinery and marine vessels will find this horn useful. It’s aimed at users who need a durable, weatherproof alarm with a distinctive dual-tone sound that’s engineered to be heard in demanding work and traffic environments. If you require a compatibility check or wiring guidance, consult a certified vehicle electrician to ensure correct installation and compliance with local sound regulations.
