Hear these horns now!

Looking for a ridiculously loud horn kit, but want something higher-pitched than a train horn? Give our Bullet 127H Nightmare Edition Air Horn Kit a shot! With this kit, you get one of the loudest air horns kits you can buy in a compact package that goes easy on your wallet. Our Bullet 127H Air Horn Kit makes the perfect beginners kit, with most of the kit pre-wired and pre-plumbed which makes for a fast and easy installation. 

They say that big thing sometimes come in small packages and this is especially true for our Bullet 127H Nightmare Edition Air Horn Kit. While this metal quad-bell horn might have an incredibly small install footprint, the tremendous sound this horn produces is even louder than some train horns we carry! Our Bullet Air Horn comes with the required 1/4" valve already pre-installed so you are back out on the road and honking in no time at all! 

Much like our Bullet Stealth Black Air Horn, our 127H Air Source Unit that it's paired with packs a lot of punch in a small package. With one of the smallest installation footprints out of all of our complete kits, our 127H Air Source Unit is perfect for installs where space is limited. The 1.5-gallon air tank for the unit can supply your Bullet Air Horn with enough air for 4 seconds of continuous blast-time and the swift Viair 275C will recharge the tank from 90-120 PSI in only 35 seconds!  

As with all HornBlasters kits, our Bullet 127H Air 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...)

**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 model kits. **
