Boost your vehicle’s presence on the road with the ROADWEST 12V/24V 4 Trumpet Train Air Horn Kit with Compressor. Built for drivers who demand a powerful warning sound, this classic horn kit delivers up to 150 dB of loud output and is suitable for cars, trucks, pickups, boats, motorcycles, buses, jeeps and more.

The kit includes four chrome-plated metal trumpets in different lengths (approx. 165 mm / 230 mm / 300 mm / 350 mm). The upgraded internal structure is engineered to push more air and produce a deeper, more aggressive tone compared to standard horns.

Designed to work with both 12V and 24V systems, this air horn kit is easy to install and flexible enough to be moved from one vehicle to another. It comes with a compressor, basic mounting hardware and hose, making it a practical upgrade for truckers, off-road builds, RV owners and marine use.
