Is there a difference from a train horn and the one the big rigs use? Awhile back on the I-17 in phoenix here some jerk in a big truck don`t recall whether it was a Superduty or not let his "train horn" rip in rush hour traffic HOLY bleep you would`ve thought that it was armegeddon people were breaking their necks looking around to see where the hell the asteroid was going to impact.

 

Not to bump an old thread, but you did an awesome job on the install. Gave me a lot of pointers for my upcoming train horn install. I like the extra port you installed to hook an air hose to on the go.
