The Kleinn “Sentinel” ABS Triple Train Horns (Model 500) are designed for drivers who want authentic train horn performance in a lightweight, cost-effective package. It delivers a deep, commanding locomotive tone while maintaining a compact footprint that fits a wide range of vehicles.
Built from chrome-plated high-impact ABS, this horn system provides excellent durability and corrosion resistance without the added weight of steel horns. The three precision-tuned trumpets (16", 14", and 11") create a balanced harmonic chord that closely mimics a real train horn.
Additional features include a Vortex™ 4 solenoid for fast response, high-pressure operation around 140–160 PSI, and a triangular aluminum mounting bracket that supports flexible installation options.
Engineered with universal fitment, the Sentinel can be mounted underbody, on frames, or even rooftop configurations depending on your build.
Installation is typically a bolt-on process when paired with an onboard air system (compressor and tank required).
Whether you're upgrading for daily driving safety, towing awareness, or stepping into the world of train horns, the Sentinel delivers reliable performance and unmistakable sound. Now Available at LEER!
