The Most Flexible Train Horn Kit Around
This is both our customers’ and installers’ favorite train horn kit. It is easily installed on almost anything. Given that there is no shared manifold for the horns they can be placed anywhere and in any direction!
This gives massive freedom for their installation; we’ve seen them inside of bumper cavities, inside of engine bays, running along frame rails, and many other places, but no matter where you install them the sound will be completely overwhelming!
These sounds these horns make is omni-directional. No one will be able to tell where it came from. Why buy a large bulky horn that’s hard to install when an all-inclusive train horn kit with this kind of flexibility is at your fingertips.
