Kleinn Black Dual Horn/ 13In/8In - High Impact ABS Trumpet/ Zinc Alloy Base

These train horns are designed for durability, easy fit and extreme sound. The ABS trumpets with extra-wide bells produce a bone-rattling locomotive horn blast that can be felt as well as heard. The 220's feature two separate mounting air horns, each with their own solenoids.
