This four piece train horn assembly is built rugged, compact, lightweight and proudly in the U.S.A!  Constructed of fiberglass reinforced ABS plastic (lightweight and extremely durable), these horns can be installed separately so they fit almost anywhere on pretty much every car or truck.  The installation possibilities are endless!

The horns also feature power air flow technology that allows them to use very little air to create a loud sound, and let you honk the horn for longer. They not only have a genuine locomotive train sound but at 148db at only 100PSI and a 2 year warranty.
