Did you know that it is possible to install a train horn on a semi? It’s true. A few years ago my buddy and I were talking with some guys at a truck stop. After a while the conversation turned to train horns. These guys told us that Train horn kits are available for relatively cheap prices on the Internet. My buddy laughed when he heard about this. He told us that train horns belong on trains not on trucks. As for me, I haven’t yet decided whether he is right or wrong about this, but I do have to admit that it would be pretty cool to have a train horn on my rig.
