Tallew 12V 150 dB Train Air Horn 2-Pack for Truck Boat Car — Black, Complete Compressor Kit

The Tallew 2 Pack 12V 150 dB Air Horn kit delivers an instant, attention-grabbing train-style blast for trucks, boats, and cars with a complete compressor, relay, and wiring kit.

This twin-pack air horn set provides everything needed to upgrade standard vehicle signals to a powerful, long-range alarm. Built from chrome-zinc horns and a weather-tolerant compressor, the kit is engineered for heavy use in automotive, marine, and utility applications. The system is serviceable, includes wiring and relay, and supports installation either as a single-horn upgrade or multiple horns in sequence depending on your audibility needs.

How loud is this horn and where will I hear it from?

The horns are rated up to 150 decibels at source, producing a sharp, train-like tone designed to be heard well beyond normal road noise. Actual perceived loudness depends on mounting location, open space, and obstacles, but the compressor and horn sizing maximize sound projection for safety alerts. Use in open-air environments such as highways, marinas, or work sites yields the best long-range effect.

• Peak output up to 150 dB for strong, clear alerts
• Train-style tone cuts through traffic and ambient noise
• Effective for long-distance warning in outdoor settings

What components are included and how does installation work?

Each pack contains two complete horn assemblies, air compressors, a relay, and a wire harness ready for vehicle wiring. The relay should handle more than 10A of current; mount the compressor securely and route air and electrical lines away from heat and moving parts. Basic mechanical and electrical skills are required; professional installation is recommended if you are unfamiliar with vehicle wiring.

• Two chrome-zinc horns with mounting hardware
• Two durable air compressors and solenoid valves
• Relay and wire harness included for straightforward wiring

Will the horn withstand weather, saltwater, and heavy use?

The horns are formed from chrome-zinc to resist rust and deformation, and the compressor uses enlarged coils to maintain stronger air pressure under load. The kit is designed to operate across a wide temperature range (-40 to 80 °C) and exceeds 100,000 duty cycles in service life expectations when installed correctly. Regular maintenance—tightening fittings and cleaning the inline filter—keeps sound quality consistent and prevents blockages.

• Chrome-zinc construction for corrosion resistance
• Compressor built for higher pressure and durability
• Temperature-rated and serviceable components for long life

How can I adapt the horns to different vehicles and needs?

This system is compatible with 12V electrical systems and suits cars, trucks, SUVs, motorcycles, boats, and commercial vehicles. You can install one or multiple horns in series to reach the desired volume and tone; mounting location and pipe routing influence performance. Ensure your vehicle’s electrical system and relay match the kit’s current requirements to avoid overheating or underperformance.

• Works with most 12V vehicles including boats and trucks
• Modular use—install single or multiple horns as required
• Check relay rating and wiring for safe operation

Who is this for: The Tallew 2 Pack 12V 150 dB Air Horn kit is aimed at drivers and vessel owners who need a robust, high-volume warning system—tow truck operators, marine skippers, off-road enthusiasts, and fleet managers who want a durable, serviceable upgrade over stock horns. It’s also suited to custom vehicle builders and anyone who needs a reliable, long-range audible alert when visibility or traffic conditions demand maximum attention.
