FARBIN Air Horn 24v Train Horn Truck Horn with Compressor - Loud Dual

Our review of the FARBIN Air Horn 24v finds it best suited for owners of 24V commercial vehicles who need a simple, high-volume upgrade without adding bulky air tanks. The bottom line: this dual-trumpet set uses chrome-plated ABS trumpets and an integrated compact compressor to deliver a very noticeable warning tone, and it installs with only two power connections. For drivers of trucks, buses, trains or heavy equipment who want a rugged, straightforward horn that prioritizes loudness and durability, this is a practical choice.

Key Features

• Chrome-plated ABS trumpets: The polymer trumpet surfaces are chrome plated to resist corrosion and maintain appearance in external environments.
• Aluminum alloy base: The horn base is made from high-quality aluminum alloy with black paint for durability across varied temperatures.
• Compact compressor: The upgraded compressor has a long red copper coil and vacuum chrome plating for fast response without a separate air cylinder.
• 150 dB output: The horn is capable of producing a very high sound level for strong audible presence in traffic and work zones.
• 24V compatibility: Designed to work on any 24V vehicle including trucks, buses, excavators, trains and ships for broad fitment.
• Simple installation: Installation requires only connecting two wires on a horn relay to a 24V power source for quick setup.

Who It's For

This horn suits professional drivers, fleet operators and owners of heavy equipment who run 24V electrical systems and need a no-nonsense audible upgrade. It is particularly useful where space is limited and installing a separate air tank is impractical.

Those who want perfectly accurate advertised levels or who need an integrated wiring harness and relay included should look elsewhere or plan for minor additional parts; a handful of users reported issues with supplied wiring or relay components, so buyers should be prepared to use their own wiring or spares if necessary.
