FARBIN Air Horn for Motorcycle Train Horns for Car Truck 150DB Super Loud Car Horn 12V with Button Compatible with Motorcycle with Horn Cover (12V, Silver Shell with Button)

This FARBIN kit is functionally identical to the previous silver shell model (integrated 150DB air pump system) but crucially includes a dedicated button and wiring for activation. This is a game-changer for motorcycle riders, as it allows the user to easily wire the new loud horn separately from the factory horn, enabling the rider to choose between the stock chirp (for courteous situations) and the 150DB train blast (for emergency situations). Its upgraded air pump and high-temperature tolerance ensure reliability, making it one of the most versatile and practical solutions for getting the best motorcycle train horn sound.

Key features that stand out: Dedicated Activation Button: Allows separate use from the OEM horn circuit. 150DB Integrated System: Powerful sound without an external compressor. Robust Pump: Upgraded pump operates reliably in extreme temperatures.

• Cons: – Finding space for the additional switch/button might require modification to the handlebars.
• Best for: Riders who want the option of using a low-volume stock horn alongside their powerful train horn.
• Expert Opinion: The inclusion of the button is a key practical feature that significantly improves usability on a bike. This dual-horn functionality makes it extremely useful in varied riding environments.

Loudness vs. Logistics: Comparison Insights

When reviewing these options for the best motorcycle train horn, there are two key variables to consider: raw sound output and physical installation footprint. Systems that rely on a separate air compressor and large trumpets, like the BOTAOSS 600DB, deliver a deeper, sustained train tone but demand considerable mounting space—often too much for a standard sportbike or cruiser.

In contrast, the electric snail horns (like the ZJLWYZQQ and the Silver 300DB Super Loud models) are far easier to mount as they contain all components in a single housing. While their decibel claims are often high, they produce a sharper, highly effective alerting sound rather than the resonant rumble of a true air horn.

The sweet spot for most riders is the integrated air horn design found in the FARBIN 150DB models. These units strike an excellent balance, producing a powerful 150dB air-driven sound while keeping the physical profile compact. For all-weather commuting, remember that the AOLIHAN Marine Horn offers superior stainless steel waterproofing, making it incredibly robust even if it’s slightly less loud than the train-style units.

Final Verdict: Choosing Your Auditory Edge

Selecting the best motorcycle train horn requires deciding what you value most: pure sound volume, ease of installation, or dual functionality.

If maximum auditory impact is your priority, even if it means complex installation: Go with the BOTAOSS 12V 600DB Air Horn Dual Trumpets. Its dual-trumpet system provides the closest experience to a full-sized train horn.

If you need the best balance of volume, reliability, and compact size: The FARBIN Air Horn (Silver Shell with Button) is the winner. The integrated 150dB system is reliable, highly loud, and the added separate activation button makes it incredibly practical for everyday use on a bike.

If you need a significant upgrade on a tight budget with minimal hassle: The ZJLWYZQQ 300DB Super Loud Train Horn delivers excellent volume for a low price point and minimal installation demands.

Frequently Asked Questions About Best Motorcycle Train Horn Systems

Are motorcycle train horns legal for street use?

The legality of using a motorcycle train horn varies significantly by jurisdiction. In many areas, the law specifies a maximum decibel limit (often around 110-120dB) and prohibits horns that produce an “unreasonably loud or harsh sound.” While you are highly unlikely to be cited just for installing one, using a 150dB or higher air horn non-emergently in urban areas can lead to a noise violation ticket. Most riders install them for genuine emergency use only.

How much current (amperage) do these loud horns draw?

Loud horns, particularly the electric snail horns claiming 300DB, can draw significantly more amperage than a stock horn (which usually draws 4–6 amps). Many powerful electric horns can draw 15–20 amps momentarily. Systems that include separate air compressors, like the BANHAO or BOTAOSS, will have high current peaks when the compressor cycles. It is absolutely essential to use the included relay and fuse kits to protect your motorcycle’s factory wiring harness from this increased load.

Do I need a full air compressor system to get a loud train sound?

Not necessarily. You need an air compressor system (like the GAMPRO or BOTAOSS) if you want the deep, sustained, classic resonant train horn tone. If your goal is simply a startlingly loud, high-decibel warning blast, a modern compact electric snail horn (such as the ZJLWYZQQ 300DB) will often suffice without the need for additional air tanks or bulky components.

What is the primary benefit of installing a train horn on a motorcycle?

The primary benefit is safety and self-preservation. Due to their small profile, motorcycles are often overlooked by distracted drivers. A traditional stock horn often fails to penetrate the noise of a driver’s stereo or an insulated car cabin. Installing the best motorcycle train horn provides the auditory authority required to immediately alert inattentive drivers and pedestrians, potentially preventing serious accidents.

What is the difference between a snail horn and a trumpet horn?

Trumpet horns (like the GAMPRO) are long, straight horns that require an external air compressor to generate a deep, resonant, traditional sound. Snail horns (like the FARBIN and ZJLWYZQQ) are typically integrated electric units where the sound coil is coiled in a compact housing, often generating a sharper, higher-pitched, but still very loud, sound without needing external air components. Snail horns are generally easier to install on motorcycles due to their compact size.

Will installing a new horn system void my motorcycle’s warranty?

Installing accessories usually does not void the entire warranty, but it can void the warranty specifically related to the electrical system if the installation causes damage (such as a short circuit). To avoid issues, always use a dedicated wiring harness with a relay and fuse that connects directly to the battery, rather than splicing into the factory horn wiring, especially when installing a powerful best motorcycle train horn system.
