The lowest priced complete train horn kit, the Black Outlaw 127H, is not a train horn kit to be underestimated. We built this kit for the value shopper; that said, we didn’t over look any of the features that make our horn kits the best on the market. This horn kit features a fast filling 120 PSI air system, a loud Outlaw 3000 train horn, and all the fitting and wiring accessories you’ll need.



If you're looking for something loud that won't burn a whole in your wallet, this is the kit you need. This kit beats all other train horn kits in its price range. Not only does it provide an all-inclusive train horn system, including D.O.T. 200 PSI rated air line, all the electrical parts, wire, and fittings you'll need, but you also get a one year warranty on the included Viair air source unit. Unlike cheap no-name air supplies, this 1.5 gallon (5.7 liter) Viair unit is reliable, efficient, and covered by warranty. Don't gamble with your investment; buy a train horn kit that exceeds your expecatations!(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...)
