Upgrade your vehicle's sound system with this powerful 12V electric horn, engineered to produce a commanding 105-115dB sound level that cuts through traffic noise. Whether you ride a motorcycle, drive a car, operate a truck, or pilot a boat, a reliable horn is critical for safety, providing a clear audible warning to other road users. This compact air horn operates over a wide temperature range from -20 to 40°C, making it suitable for year-round use in the UK. With a choice of Black or Red finish, it combines functional performance with practical design.
Features and Construction

This horn is built around a robust electrical design that delivers a loud dual-tone output without excessive power draw. Its construction focuses on durability and ease of installation for various vehicle types.
Sound Output and Power
The horn produces a rated sound level between 105 and 115 decibels, which is significantly louder than many standard factory-installed horns. This high output ensures your warning is heard in busy urban environments or on motorways. It operates at 60/50W from a standard 12V DC electrical system, allowing straightforward connection to most motorcycle, automotive, marine, and light truck electrical setups.
Size and Practical Fit
Measuring 220mm in its longest dimension and 170mm in the shorter one, the horn is compact enough for installation in space-constrained areas like under fairings, behind grilles, or in engine bays. The dual-length design helps produce a richer tone while maintaining a manageable footprint for universal mounting.
Uses and Placement

This horn is suited for a wide range of vehicles where an audible warning is legally required or recommended. Its robust construction means it can be used both recreationally and professionally.
Event or Professional Use
For professional drivers, event organisers, or fleet operators, a loud horn provides an extra layer of safety when manoeuvring in busy yards, docks, or event spaces. The 12V compatibility makes it easy to retrofit onto older vehicles or as a replacement for worn-out factory units.
Everyday Home Use
Motorcyclists and car owners will appreciate the peace of mind from a horn that can signal effectively in emergency situations. The red or black colour options allow you to match the horn to your vehicle's aesthetic, and the durable metal finish withstands typical weather exposure.
Benefits and Buying Value

Investing in a higher-sound-level horn can improve your on-road safety without requiring specialised installation skills. This model offers a balance of performance and practicality.
Reuse and Low Maintenance
With no moving parts beyond the internal diaphragm, this electric horn requires minimal maintenance beyond periodic testing and cleaning of electrical contacts. The sealed construction helps protect against moisture ingress during normal use.
Why Choose This Product
If your current horn is too quiet or unreliable, this 12V air horn provides a straightforward upgrade. It delivers a loud, clear warning sound backed by a simple electrical design, available in two colours to suit your vehicle.
