Tallew 12V 150 dB Air Horn Dual Pack — Black, Chrome‑Zinc Trumpets with 12V Compressor & Harness

The Tallew 2 Pack 12V 150 dB Air Horn is a complete dual-horn kit that delivers an exceptionally loud, attention-grabbing 150 dB warning tone for trucks, boats, cars and other 12V vehicles.

This dual-kit train-style horn bundle combines two chrome-zinc trumpet horns, a heavy-duty 12V air compressor, relay and a wired harness so you can add a powerful, serviceable horn system to a wide range of vehicles. Built to resist rust and temperature changes, the components are designed for frequent use and straightforward installation by owners who want a louder, more authoritative signaling option than stock horns.

How loud is this air horn and where can I use it?

The horns are rated up to 150 decibels at peak output, which is intentionally very loud to grab attention in noisy environments. That volume level is suited for marine, commercial and off-road use where a standard horn may be drowned out.

• Peak sound: up to 150 dB per kit.
• Suitable for 12V systems on cars, trucks, buses, boats and SUVs.
• Effective in open-air, congested traffic and marine settings.

What components are included and how reliable are they?

The package contains two full horn kits: dual trumpets, a 12V air compressor, relay and a wire harness for each set. Materials and build quality—like chrome-zinc trumpets and a compressor with a larger coil—are chosen for durability and weather resistance.

• Two complete horn sets for staging or backup use.
• Chrome-zinc trumpets resist corrosion and deformation.
• Compressor has a reinforced coil for steady air pressure and longevity.

How difficult is installation and what wiring should I know about?

Installation is intended to be straightforward for mechanics or competent DIYers: mount the horns, secure the compressor, connect the relay and run the harness to a 12V power source and switch. To avoid issues, use a relay rated above 10A and ensure all air fittings are tightened to prevent leaks.

• Includes relay and wired harness for direct connection to 12V systems.
• Recommended relay current: greater than 10A for reliable switching.
• Tighten solenoid valve fittings and keep the compressor filter clean.

What maintenance and operating conditions should I expect?

The horn system is serviceable and built for repeated use with a rated life above 100,000 cycles under normal conditions. It tolerates a broad temperature range but benefits from routine checks to maintain performance.

• Temperature adaptation: -40°C to 80°C for consistent operation.
• Service life: more than 100,000 activations when maintained.
• Routine care: clear air lines, clean filter and tighten connectors to preserve sound quality.

Who is this for? The Tallew 2 Pack 12V 150 dB Air Horn is aimed at drivers and vehicle owners who need a louder-than-stock audible warning: commercial drivers, boat owners, off-road enthusiasts and anyone modifying a 12V vehicle for greater roadside or on-water presence. If you need a robust, ready-to-install horn kit with durable materials and high output for busy environments, this kit delivers the parts and specs to meet those demands.
