The AH-D300+ gives drivers a detachable 3-tone train horn assembly with chrome-plated brass trumpets. The 10.5-inch, 14.5-inch, and 15-inch trumpet sizes deliver the aggressive sound customers expect from a true train horn setup.

Because the trumpets can be detached from the manifold, installers have more flexibility when planning tight or custom vehicle layouts. Remote-mount hose kits should be selected separately when the trumpets are mounted away from the manifold.
