I put a train horn on my F250 along with a lightbar to make it a volunteer firefighter's POV with a train horn.The owner of Arkansas Traveler Hobbies in Bald Knob,AR,formerly Pine Bluff,AR,painted the horn and shaft and drilled a hole in the bed to put the horn on the truck.I put the lightbar on the roof later that evening. http://twitpic.com/3nwyqi http://twitpic.com/3nxa6z http://twitpic.com/3nxje5 http://twitpic.com/3nxug1 http://twitpic.com/3o0m1z http://twitpic.com/3o0m7d Here it is after the camcorder rode around on the store layout being pulled by my CNW & SP -9-44CWs. http://www.youtube.com/watch?v=CQn03U2qFCw
