So I've thought about adding a set of air horns off and on for several years, just never did it until now. So I bought a set of train horns and mounted them under the truck on the right side under the bed. Next up was a Viair compressor to power them. It came with a 2 gallon air tank and pumps up to 200 psi. Eventually, I may do some additions to be able to air up the truck tires with it, but for now, it's for the horns. I also found a pretty neat device to actuate the solenoid valve that controls the horns. It's a 12VDC wireless operated switch. You provide 12V to the board to operate it and 12V to a set of contacts (rated at 10 amps). It comes with two key fob remotes, similar to a car/truck key fob and it operates at 433 mHz. So the key fob button activates the relay, which in turn operates the solenoid valve, which in turn makes the air horns blow. Me likey!
