27000. (a) A motor vehicle, when operated upon a highway, shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than 200 feet, but no horn shall emit an unreasonably loud or harsh sound.

EDIT - I looked up the regs for Georgia and they are the same as CA.

O.C.G.A. 40-8-70 (2010)
40-8-70. Horns and warning devices
(a) Every motor vehicle when operated upon a highway shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than 200 feet, but no horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle. The driver of a motor vehicle shall, when it is reasonably necessary to ensure safe operation, give audible warning with his or her horn but shall not otherwise use such horn when upon a highway.

Funny story...went to Les Schwab yesterday to have my tires rotated. I'm waiting around in the lobby on my computer and after a bit i hear a slightly higher horn than you would normally hear. I think to myself, "He's resetting the TPMS and i left the upfitter switch on." So i hear it go off 2-3 times as he's going around the vehicle to each tire when one of the techs comes walking in and he says to one of his co-workers, "theres a train horn on that thing!" I look at him and i say "SO SORRY! You can shut it off by just flipping the upfitter #1." He responds back with "oh don't worry about it, he's almost done anyway, plus it's a good wake up in the middle of the day." So i leave it be at this point. Then i proceed to hear the train horn go off probably another 10 times. Pretty sure he was either not getting the TPMS's reset correctly, or just liked hearing the horn in their shop

The Kleinn kit above is the only bolt-on kit. Kleinn and Hornblasters are generally high quality, high cost horns. Nathan are real train horns and cost a small fortune. You can get about as cheap as you want, just search on Amazon. On-board air is obviously required. Viair makes several kits, but there are other brands, too. A good, high quality 100% duty cycle + 2-3 gallon tank will be in the $300 - $400 range. Stand-alone horns will be $100 - $400 ... maybe 3-4x that for Nathan. So, you'll be into it $500 - $800 for the air and horns.

Then, install. You'll need to figure out how to do this, if you don't pay the premium for the Kleinn kit. Some remove their spare tires and install up there. Some install along the frame rails. Either way, you'll probably be into it another $100 for various sheet metal and angle-iron to craft mounting brackets. You'll be into it another $50-$100 for connections, hose, and other installation gear.

I would love to have on-board air. Train horns are a nice to have ... there are times going up I-70 towing a trailer that having an air horn would be nice ... just like it's nice for the big rigs to have an air horn.

I wired my truck's horn button, through a relay controlled by a rocker switch on my dash. That way, I could run regular horn at home and around town and then just flip the switch over to get the air horns when I was on the highway or if I just needed them for a "Special Occasion"!!! I'd love to do my new 2019 F-450... but at 70 years old and after 3 back surgeries, I just can't do it anymore! :-(

And yes, I do live to impress and put smiles on my young children's faces.
