A train horn kit designed for the value shopper, our Outlaw 228H black train horn kit brings a massive sound in a small package. With a wallet-friendly price and incredibly simple installation, our Outlaw 228H black train horn kit has been the go-to kit for anyone new to train horns.

Our Outlaw black train horn may not seem imposing at first glance but this only adds to the surprise upon hearing them as these 3-chime metal horns are some of the loudest horns that we carry. Our Outlaw train horn comes in a stealth black finish and comes with the required 3/8" solenoid valve already pre-installed for you.

The HornAir 228H air source unit we paired with our Outlaw black train horn is designed with the train horn beginner in mind. Our 2-gallon tank provides enough air to give your Outlaw train horns a honk time of up to 5 continuous seconds and the pre-mounted Viar 280C Air Compressor will recharge the tank from 110-145 PSi in only 1 minute and 15 seconds. With a lot of the system already pre-wired and pre-plumbed for you, installation is easy and the install footprint is perfect for the trunk of a car or a toolbox of a truck.

Our HornAir 228H air source unit is designed to be installed somewhere dry and free of debris, so keep that in mind when planning your installation.

  • Heavy-duty black finish
  • 150 PSI air system
  • All-inclusive train horn kit
  • Max honk time: 4-6 seconds

(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... Failure to mount this product as directed will void the warranty)

**Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models. **

Too much fun!!

We installed this on our 58 Impala. This horn was made for this vehicle!! The sound is spot on and definitely turns heads. It has been an attention getter upon arrival and departure from many car shows. Highly recommend!! Easy to install!

The install was somewhat difficult probably because of my truck. I had to make some extra brackets and buy an extra fuse and get some extra wire. But that’s about it, would recommend going to a shop honestly.

Beautiful Horns!!!

Horns are great quality, relay wiring hookup needs good detailed directions since kit comes with a relay, they’re a bit difficult to install, but the outlaw is the lawless renagade.
