Powerful, attention-getting sound

The dual-tr trumpet layout produces a commanding blast, with a 120dB rating that helps your signal carry over ambient road noise and weather. The result is a sound that's noticeable at longer distances, helping you be heard when it matters most.

• Ultra-loud 120dB signal designed to cut through traffic noise
• Dual trumpets for a fuller, more recognizable tone
• Ideal for trucks, SUVs, off-road rigs, and boats seeking enhanced signaling

Upgraded compressor for stronger performance

An upgraded air compressor paired with a larger coil delivers more air pressure, producing a louder and clearer tone even in challenging acoustic environments. This setup supports reliable operation in safety and emergency signaling scenarios.

• Stronger air pressure for louder, clearer sound
• Enhanced performance in noisy or windy conditions
• Designed to respond quickly when signaling is needed

Durable, weatherproof build

Constructed from a durable ABS-plastic and iron mix, the horn is designed to be waterproof, rustproof, and corrosion-resistant. This means you can rely on it in rain, salt spray, and everyday use without compromising sound quality.

• Waterproof and corrosion-resistant for long-term reliability
• Rugged materials suited for outdoor and marine environments
• Built to withstand common road and weather conditions

Easy to install and widely compatible

The kit is compact and designed for quick, straightforward installation. Wiring is simple—red wire to power and black wire to ground—while mounting brackets offer flexible placement options. For optimal sound, ensure the horn opening is unobstructed and away from hot engine components.

• Compact, plug-and-play installation with mounting brackets
