12V/24V 17" 150dB Single Trumpet Car Air Horn Kit

A horn that makes sure you are heard, wherever the road takes you.

This single trumpet air horn puts out a focused 150 dB blast at 180 Hz, so your vehicle cuts through busy traffic and noisy conditions. The trumpet runs about 17 inches (450 mm) long with a 95 mm bell width, and it suits cars, trucks, SUVs, vans, boats and other vehicles on 12V or 24V systems. A compact air compressor supplies the pressure, so you do not need an onboard air tank.

Why we picked it

• Loud and clear - 150 dB at 180 Hz carries a low, steady tone across long distances.
• Fits 12V or 24V - works with passenger cars, light and heavy trucks, motorcycles, RVs and marine setups.
• Ready to install - ships with the trumpet, compressor, air hose, screws and brackets.

Good to know

The kit includes 1 trumpet, 1 air compressor, 1 air hose and a bag of fixings (screws and brackets). The chrome-style finish keeps the look clean. Connector screw color may vary. Basic electrical and mechanical skills are enough for most self-installs; go professional if you are unsure.
