Our loudest marine horn teams up with our most popular air-source unit to bring you a budget-friendly kit that’s just at home in the harbor as the highway. Our Outlaw XL 127H train horn kit is a force to be reckoned with. Designed and built to withstand the elements out at sea, our Outlaw XL train horn is just as durable as it is loud. Coupled with our 127H, this kit brings you all the power you need without breaking the bank. 

Constructed from brass and coated in a beautiful chrome finish to prevent rust, our Outlaw XL train horn is designed to last forever and shine for years to come. This three-chime train horn also happens to be one of the loudest horns we carry! While our Outlaw XL train horn was designed with our maritime customers in mind, due to its huge sound and dazzling chromed-out finish, it can also be found on many trucks as well! Our Outlaw XL Chrome Train Horn comes ready to honk with the required 3/8” valve pre-plumbed for you. 

With our HornAir 127H air source unit, you don’t need a thousand-dollar budget to get train horns on your ride. We packed all the performance needed to power some of the loudest train horns you can buy in a compact package, priced for the value shopper.  Our HornAir 127H air source unit comes pre-wired and pre-plumbed, making installation much quicker and simpler than other horn kits. Our 1.5-gallon tank provides enough air for up to 3-5 seconds of blast time! On top of that, the Viair 275C Air Compressor we paired with this tank will recharge the system from 90-120 PSI in a stunning 35 seconds.

  • Heavy-duty chrome finish
  • 120 PSI air system
  • All-inclusive train horn kit
  • Max honk time: 3 to 5 Seconds

As with all HornBlasters kits, our Outlaw XL 127H train horn kit comes complete with all required components and detailed instructions.

(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. **
