With the increasing number of distracted drivers on the road, many times a stock horn won't cut it. With our Safety 127H air horn kit, you will no longer be ignored on the road! Perfect for anyone who wants a simple and cost-effective way to get a horn that will turn heads. 

Our Safety air horn is a single-chime metal-air horn with a punchy mid-range tone most similar to a firetruck. Distracted drivers are sure to clear your path when they hear you coming, earning our Safety air horn’s namesake and making the road a little safer for you. Our Safety air horn has the 3/8" electric air valve pre-installed to make installation even easier!

We paired our Safety air horn with our most popular entry-level air source unit, the HornAir 127H air source unit. This self-contained unit has everything needed to provide a safe, reliable, and worry-free 12-volt onboard air solution. It comes complete with a safety blow-off valve, drain cock, pressure switch, and a compression fitting, making this unit the perfect air source solution for lightweight and compact applications. Our Safety 127H air horn kit comes completely pre-plumbed and pre-wired saving you time and energy!

  • All-inclusive air horn solution!
  • Complete with pre-installed air valve & fittings
  • 120 PSI Air system
  • Max honk time: 3 to 4 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. **
