Dual trumpet arrangement driven by a 12V electric compressor produces a rich, resonant tone. ABS body and chrome-plated zinc alloy trumpets provide waterproof, corrosion-resistant durability.


Unmistakable warning power - with 150dB dual trumpet output

A 12V electric compressor pressurises air and forces it through two chrome-plated trumpets, creating a high-decibel, low-frequency tone that carries through ambient noise. Dual trumpets produce a layered sound with greater penetration than a single horn.

A commanding alert improves visibility and helps make other road users aware quickly during urban traffic or on open water.

All-weather durability - thanks to ABS and chrome-plated zinc alloy construction

ABS housing resists impact while chrome-plated zinc alloy trumpets resist corrosion, and seals on the compressor provide waterproof protection. Materials are chosen to withstand wet and salty conditions common in marine and winter use.

Long-term resistance to rust and moisture means reliable operation through rain, spray and seasonal conditions.

Quick fit across vehicles - with universal 12V compatibility and included hardware

Designed for 12V DC electrical systems, the kit includes a wiring harness and mounting hardware for direct connection to existing vehicle circuits. The wiring layout keeps installation straightforward without specialist tools.

A straightforward DIY install reduces downtime and gets a louder, more effective warning in place quickly.
