Perfect for anyone that wants to hurt their ears and not their wallet, it’s no surprise that our HornBlasters Outlaw 232 black train horn kit is one of our most popular complete horn kits. Bringing a huge train horn sound and volume at an entry-level price, our Outlaw 232 train horn kit is the go-to for many of our customer’s first kit.

Our Outlaw black train horns are some of the loudest horns that we carry. With three black wide-flare metal bells on a metal bracket, not only will they give you that thunderously loud and low train horn sound, but they will give you an authentic train horn look and feel. Our Outlaw black train horns come in the popular stealth black finish, just like many train horns used today!

We paired our best entry-level train horn with our best entry-level onboard air system, the Horn Air 232 onboard air system. Alongside our 2-gallon black 6 port air tank is a Viair 380C air compressor and while the pricing may be entry-level, the performance is far from it. The constant duty Viair 380C air compressor can recharge our 2-gallon tank from 110 to 150 in just under a minute. Though it isn't considered a heavy-duty or constant duty like other compressors in its class, it can still support light pneumatic uses such as emergency tire inflation or load leveling.

I love this train horn! It was much louder than expected. I scared myself the first time I hit the button!

I was very impressed with the sound/volume of this train horn. It was also much easier to install than expected; it fit perfectly tucked up where I used to keep my spare tire.
