Horns and Accessories for Truck, Jeep and Car Air Horns

What This Horns and Accessories Collection Covers

The Horns and Accessories collection covers audible warning upgrades and the supporting electrical or air system parts needed for a complete installation. It includes compact electric horn replacements, high output trumpet systems, onboard air packages, vehicle specific Hella brackets, and wiring kits for popular truck, Jeep, and Subaru platforms.

Electric Horns and Trumpet Horns

Select the right sound and package

Electric disc and trumpet horns provide a compact upgrade while larger air systems deliver a more commanding output. Compare voltage, mounting space, tone, current draw, and local regulations before choosing a system.

Air Horn Systems

Compressors, tanks, and lines

A complete air horn setup can include horns, compressor, tank, pressure switch, relay, wiring, air line, and mounting hardware. Match compressor duty cycle and tank capacity to the expected use.

Vehicle Specific Brackets and Harnesses

Clean installation for supported vehicles

Hella horn harnesses and brackets are available for selected Subaru WRX and STI applications. Truck kits can include brackets and plumbing that place the horns and air components around the chassis layout.

Electrical Control and Protection

Relays, fuses, and switches

High output horns can require a dedicated relay, correctly sized fuse, and wire gauge appropriate for the current draw. Protect all wiring, seal connections, and route harnesses away from heat and moving components.

Mounting and Legal Considerations

Plan the installation responsibly

Install horns securely and keep air lines, wiring, and compressor components clear of suspension travel, exhaust heat, and road debris. Check state and local rules regarding horn volume and use.

Common Questions

Do aftermarket horns need a relay?

Many high output horns and air horn systems use a dedicated relay to handle current safely. Follow the horn manufacturer wiring instructions for the selected kit.

What is included in an air horn kit?

Contents vary, but a kit can include horns, a compressor, tank, air line, fittings, relay, switch, wiring, and mounting hardware. Review the listing for the exact contents.

Can I install Hella horns on a Subaru WRX?

Vehicle specific brackets and wiring harnesses are available for many WRX and STI applications. Confirm the model year and bracket or harness fitment before ordering.

Are dual trumpet horns louder than factory horns?

Dual trumpet systems are designed to produce a more noticeable tone than many factory horns. Actual output depends on the horn model, installation, voltage, and vehicle environment.

Can an air horn compressor be used for other accessories?

Some onboard air systems can support other appropriate air accessories, subject to the compressor duty cycle, tank capacity, and system design. Follow the manufacturer limitations.

What wire size should I use for a horn?

Wire size and fuse rating depend on the horn current draw and run length. Use the manufacturer instructions and safe automotive wiring practices.

Do horn kits fit behind every bumper?

No. Space behind the bumper and grille differs by vehicle. Check horn dimensions, bracket location, airflow, and clearance before installation.

Are air horns legal for road use?

Rules vary by location and can limit sound level or type of horn. Check state and local regulations before installing or operating an air horn system.

How do I protect horn wiring?

Use a fuse, relay when specified, weather resistant connections, protective loom, and secure mounting. Keep wiring away from heat, sharp edges, and moving parts.

How do I confirm horn fitment?

Confirm year, make, model, engine, bumper configuration, available mounting space, and electrical system requirements. Compare the product notes with the vehicle.
