With a sound that is almost criminal, our Bandit 127H air horn kit brings enough volume to wake the dead in a compact and budget-friendly package. If you're looking for something that makes your stock horn look like a kids toy, but don’t want it to cost an arm and a leg, this is the perfect kit for you! 

Our Bandit air horn is a lightweight and compact three-chime air horn that emits a high-pitched blast that is sure to get everyone’s attention. With its small installation footprint, it's perfect for smaller vehicles with limited space. Great as a starter horn, our Bandit comes with the required 3/8" electric air valve already pre-installed, making installation a breeze!

Pairing our Bandit horn with our HornAir 127H air source unit gives you one of the most cost-effective ways to get loud. With most of your plumbing and wiring already done for you, our Bandit 127H is ideal for beginners wanting to spend more time blasting their horn than installing it. While we made sure this compact kit didn’t break the bank, we made sure to bring all the performance you have come to expect from a HornBlasters Kit. Our 1.5-Gallon tank provides enough air to give your Bandit horn up to 5 seconds of continuous blast time and the incredibly quick Viair 275C air compressor mounted to the tank recharges the kit from 90-110 PSI in a stunning 35 seconds! 

As with all HornBlasters kits, our Bandit 127H air horn kit comes complete with all required components and detailed instructions.

  • Heavy-duty black finish air horns
  • 120 PSI air system
  • All-inclusive air horn kit
  • Pre-installed fittings & air valve for ease of installation
  • Max honk time: 5 to 7 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. **

Easy to install!!!!



Definently love the bandit series I got, the hookup is kinda tricky at first but the loudness is spectacular, however to whoever is looking into any kit I would recommend the spare tire delete kit. I did not get it and had to rig up some brackets and after I seen a video on how easy the spare tire delete goes in I kick myself in the butt for not getting it
