YaeTek 12V Single Trumpet Air Horn 150 dB Chrome — Compact 17.7" Loud for Trucks, Vans & Boats

The YaeTek 12V Single Trumpet Air Horn is a compact, chrome-plated zinc loudhorn delivering up to 150 dB of sound for cars, trucks, boats and other 12V vehicles.

Built for drivers and vessel operators who need a powerful audible warning from a small footprint, this single-trumpet horn packs intense volume into a slim 17.7" length. Its chrome-plated zinc trumpet resists rust and keeps a polished look on bumpers and mounts, while the 12V design makes it compatible with most automobiles, vans, lorries and marine systems that accept standard vehicle voltage.

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

The horn produces a very high sound level—measured up to around 150 decibels—so it’s intended for use in noisy environments and for situations requiring strong audible presence. Ideal mounting locations include commercial vehicle exteriors, boats, and larger private vehicles where greater noticeability is needed.

• Peak sound output up to approximately 150 dB for clear signaling
• Suitable for trucks, lorries, vans, cars and many boats with 12V systems
• Single trumpet design concentrates sound in one direction for focused reach

Will it fit my vehicle and how big is it?

This single trumpet horn is designed to fit most vehicles that run on a standard 12V electrical system. The unit is compact enough to install in tight spaces while the overall dimensions help you plan mounting and wiring before purchase.

• Overall size: 17.7" L x 3.9" W x 3.7" H to aid placement decisions
• 12V rated for compatibility with common automotive electrical setups
• Mounting hardware and wiring considerations: plan for a secure bracket and protected wiring route

What is the horn made of and how does it hold up outdoors?

The trumpet body is chrome-plated zinc, which gives the horn a corrosion-resistant finish and a professional look on vehicle exteriors. While chrome plating improves rust resistance, proper mounting and occasional cleaning will help preserve appearance and sound performance over time.

• Chrome-plated zinc trumpet for added anti-rust protection
• Durable construction suitable for exterior mounting on vehicles and boats
• Simple single-trumpet layout reduces moving parts and simplifies maintenance

How is this horn powered and controlled?

The horn runs on a 12V supply and integrates with a vehicle’s electrical system using a standard wiring connection and relay (recommended). Activation is typically via a horn button or custom switch and should follow vehicle wiring best practices for safety.

• Operates on a 12V electrical system, common in cars and boats
• Works best with an inline relay to protect vehicle wiring and ensure reliable actuation
• Simple wiring makes installation straightforward for installers or experienced DIYers

Who is this horn for? If you need a high-volume signaling device that occupies minimal space—such as fleet drivers, off-road and marine users, or anyone upgrading a factory horn—this YaeTek single trumpet air horn offers loud, focused sound with a rust-resistant chrome finish. It’s a strong choice when clear audible presence matters and you prefer a compact, easy-to-install horn compatible with 12V vehicles.
