Hear these horns now!

One of our most popular entry-level train horn kits, our Outlaw Black 127H Train Horn Kit is easy to install and packs heaps of power at a budget-friendly price. If you are wanting that authentic train horn sound for an affordable cost, this is the perfect kit for you.

As one of the loudest train horns we carry, our Outlaw Black Train Horn packs a lot more punch than it’s size would lead you to believe. With an install footprint much smaller than other train horns, our Outlaw Black Train Horn is a great alternative to larger train horns when space is limited without losing volume.

Our HornAir 127H Air Source Unit that we bundled with our Outlaw Black Train Horn is the ideal air source unit for tight install requirements or tight budgets. As our smallest air source unit, our HornAir 127H Air Source Unit can easily fit in the trunk of a car or a toolbox. As a non-enclosed unit, we highly recommend keeping the unit in a space that is dry and free of debris. While our Outlaw Black 127H Train Horn Kit might seem small, you still get a stunning 5 seconds of continuous blast time out of the gallon and a half tank and a lightning-fast recharge time of 90-120 PSI in only 35 seconds! Like all HornBlasters Horn Kits, the Outlaw Black 127H Train Horn Kit is a complete kit with all required components and detailed instructions included.

While this kit gives you everything you need to get up and going, make sure to pick up our wireless remote to get the most out of this kit!

(Note: Tank mounted air compressors are not fully sealed.  For this reason, the manufacturer recommends the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc...)

Holy Sh&t!

My order came quickly and packaged great. I opened horns and Holy crap they are huge! The compressor is nice and compact. I started the installation and there was some confusion on the length of the supplied air line. I called customer service and they were great and sent out the length I needed no questions asked. I finished installing the kit and the first blow was way louder than I ever expected. The videos don't do this thing any justice. I'm more than pleased with my purchase. If you're thinking of buying a train horn kit. This is the best value hands down!
