Thanks for the pic..... holy Stuff, that is a pita to get to
It's not as bad as it looks. Just pull the fender liner down and viola!
What does DOT law say about horns..... I would like to keep the truck legal
As I understand it, there isn't per say a law on the books that make them illegal. It's subject to your local laws/ordinances regarding noise dB levels.
Found a post stating that this is what the Ohio code is regarding it...
From the Ohio Revised Code:
(A) Every motor vehicle or trackless trolley when operated upon a highway shall be equipped with a horn which is in good working order and capable of emitting sound audible, under normal conditions, from a distance of not less than two hundred feet.
No motor vehicle or trackless trolley shall be equipped with, nor shall any person use upon a vehicle, any siren, whistle, or bell. Any vehicle may be equipped with a theft alarm signal device which shall be so arranged that it cannot be used as an ordinary warning signal. Every emergency vehicle shall be equipped with a siren, whistle, or bell, capable of emitting sound audible under normal conditions from a distance of not less than five hundred feet and of a type approved by the director of public safety. Such equipment shall not be used except when such vehicle is operated in response to an emergency call or is in the immediate pursuit of an actual or suspected violator of the law, in which case the driver of the emergency vehicle shall sound such equipment when it is necessary to warn pedestrians and other drivers of the approach thereof.
So, it looks like if the horn can be heard from more than 500 feet away it would be frowned upon. Hell, most factory horns can....
I might just have to fix the original horn, and add the trains!!!! Plus when I set the truck alarm in the middle of the night, I am sure my neighbors will love me
They already complained about my trucking being too load, and I have the stock muffler on!!!
Some of the installs I've seen either had a separate button to trigger the air horns, or they wired it up with a switch where when activated the normal horn button triggered the air horn, but when the switch was deactivated, the factory hon functioned as normal.
