Horn Accessories & Kits for Trucks

Make Your Truck Heard — Loud, Clear, Reliable

When you’re operating in busy vocational, heavy-equipment or fleet environments, a dependable horn system is not just a luxury — it’s a safety and visibility upgrade. Whether you’re alerting nearby workers, signaling a large load, or simply ensuring your rig stands out, choosing the right horn and accessories matters. From replacement horns to full kits with compressors, tanks and wiring, the right solution helps you meet your fleet’s needs and regulatory standards.

What We Offer

At Custom Truck One Source, we provide a wide selection of horn accessories and complete horn kits for trucks and specialty rigs. Our product range includes:

• Replacement horns (electric, air-driven) designed for heavy-duty vehicle use

• Complete air horn kits with compressor, tank, trumpet, wiring and mounting hardware

• Horn-system accessories such as wiring kits, switches, button assemblies, weather protection covers, and pull-cords

• Installation support and advice on choosing the right horn type for your vehicle class, body configuration, and jobsite environment

• Both new and used horn accessories to align with your budget and operational requirements

Key Features & Considerations

When selecting a horn system or accessory, consider these important factors:

• Sound level & tone pattern: Ensure the horn is loud enough and engineered for the environment (e.g., high-noise industrial yards, long-haul truck operations).

• Power source & system integration: Air-horn systems require onboard compressors and tanks; electric horns may be simpler but may not deliver the same volume.

• Durability & mounting: Choose weather-resistant components, solid mounting hardware, and accessibility for maintenance.

• Compatibility & fit-out: Match wiring, switch assemblies, and controls to chassis and body configuration, and ensure integration with your vehicle’s electrical/air systems.

• Regulatory compliance & safety: In many service environments, clearly audible and reliable horns are part of safety protocols. Ensuring your horn system meets or exceeds job-site standards is key.

Typical Uses & Industries

Horn accessories and systems are relevant for a broad range of fleet and equipment applications:

• Vocational truck fleets — dump trucks, service trucks, rail-service trucks needing audible warning systems

• Heavy equipment and off-road rigs where visual plus audible signals enhance safety on site

• Specialty vehicle conversions — hi-rail trucks, crane trucks, utility trucks — where accessory horns enhance visibility and signaling

• Replacement or upgrade situations — older equipment needing horn system refresh to meet fleet standards

• Rental and lease fleets needing standardized horn solutions for quick turnover and reliability
