300DB Super Loud Train Horns, 12V Waterproof Air Horns Replacement Kit, Car, Motorcycle, Truck, Bike, Boat Car Air Electric Snail Double Horn, Automotive Accessories Universal for Car

If 150dB isn’t loud enough, this unit claims an astronomical 300DB, making it one of the loudest available options for those who prioritize absolute auditory dominance. Built with a heavy-duty red metal housing and black trumpet, this snail horn is designed to be highly durable and waterproof, ensuring it stands up to tough riding conditions. While this is marketed primarily towards trucks, its relatively compact nature allows motorcycle users, particularly those with fairings or large engine guards, to mount it effectively.

Key features that stand out:
– 300DB Claimed Power: Designed to be heard from incredible distances.
– Heavy-Duty Construction: Durable metal housing built to withstand impact and weather.
– Waterproof Design: Ensures reliable function regardless of rain or road spray.
– Easy Installation: Includes a straightforward mounting bracket.

Pros:
– Unbelievably high claimed loudness ensures maximum attention.
– Robust, heavy-duty build quality enhances longevity.
– Simple mounting structure using an included bracket.

Cons:
– Achieving the advertised 300dB peak might require high amperage wiring not standard on all bikes.

Best for: Riders who require the absolute loudest horn possible and have sufficient space (and wiring capacity) to accommodate a very high-output unit.

Expert Opinion: The 300DB rating is attention-grabbing, but riders should be realistic about achieving that peak volume on a standard 12V motorcycle electrical system. However, even if it performs closer to 180dB, it’s still significantly louder than standard horns. The heavy-duty construction is a major positive for long-term use.

Best for: Large motorcycles (like Baggers or Goldwings) where space is less restricted and the rider prioritizes the most effective, dual-frequency warning system possible.

Expert Opinion: For riders who want that undeniable “truck horn” sound without needing to install full air tanks, this dual-trumpet kit is the answer. The upgraded compressor ensures the volume is consistently high, making it a powerful best motorcycle air horn option for highway riding.

Comparison Insights: Choosing the Right Loudness and Style

When deciding which best motorcycle air horn is right for you, consider the trade-offs between size, volume, and installation complexity.

For maximum noise output, the 300DB Super Loud Train Horns claim the highest volume, though you should verify if your bike’s electrical system can fully support this extreme draw.

If you are concerned about mounting space, the FARBIN Air Horn for Motorcycle (Personality Grey) and the FARBIN Compact Air Horn with Compressor Snail designs are superior. These “snail” horns integrate the compressor and horn into a single compact unit, drastically simplifying mounting compared to the traditional trumpet styles.

For those who prefer the deep resonance of a traditional air horn, the Train Horn for Truck 12v (Single Trumpet) and the 150db Super Loud Dual Trumpet Air Horn Kit deliver that classic sound but require you to find separate spots for the compressor and the trumpet(s), demanding a bit more planning for installation.

Finally, completeness matters. Most FARBIN kits, particularly the 150dB snail models, come with the full relay, fuse, and harness, saving you time and money compared to systems where you must source these electrical components separately.

Frequently Asked Questions About best motorcycle air horn

Is installing a best motorcycle air horn legal?

The legality of installing an extremely loud or train-style horn varies significantly by region and state. Generally, most jurisdictions regulate the maximum decibel level allowed for vehicle horns (often around 110-120dB at a certain distance). While horns rated at 150dB or 300dB are often sold, using them continuously or for non-emergency purposes may violate local noise ordinances. Always check your local motor vehicle laws regarding horn output before installation.

What’s the difference between a “snail horn” and a “trumpet horn”?

A snail horn integrates the air compression mechanism and the sound chamber into one compact, often round or spiral, unit. They are generally easier to mount in tight spaces. A trumpet horn (or train horn) consists of a separate air compressor unit connected via tubing to one or more metal trumpets. Trumpet horns often achieve a deeper, more resonant sound but require more physical space for installation.

Do I need a relay to install a loud air horn?

Yes, almost always. Factory motorcycle horns draw very little amperage (typically 3-5 amps). High-volume air horns, especially those rated 150dB or higher, can draw 15-30 amps instantly. Connecting a powerful air horn directly to your factory wiring can overheat the wires or blow your fuse box. A relay acts as a switch, using the low amperage factory horn button signal to safely trigger the flow of high amperage power directly from the battery to the new horn.

How do I maintain my air horn system?

Maintenance is minimal, especially for the compact electric snail horns. For trumpet horns, ensure the air line connections are secure and free of leaks. Regularly check that the compressor is free of debris. For all types, ensure the terminals are kept clean and rust-free (using dielectric grease helps), as moisture and corrosion can impair performance, especially in wet riding conditions.

Can I use a high-powered air horn with my bike’s standard battery?

You can, provided you use the proper wiring and relay setup. Air horns draw high amperage, but only for a very short duration. A typical 12-volt motorcycle battery can handle this momentary spike. The key is ensuring your wiring harness is properly fused and directly connected to the battery terminals (via the relay) to avoid overloading the bike’s existing electrical system.

How much louder is a 150dB air horn compared to a stock horn?

The average factory motorcycle horn ranges from 90dB to 100dB. The decibel scale is logarithmic, meaning an increase of 10dB roughly doubles the perceived loudness. Therefore, a 150dB horn is exponentially louder and more attention-grabbing than a stock horn. This significant jump is what makes upgrading to a best motorcycle air horn such a vital safety measure.
