Wolo, the first company to offer ABS plastic train horns to the public has finally solved the problem of wanting a brawny sounding horn without taking up a ton of space: the Express Pro Train Horn. A universal flat rack design makes installation easier than almost any horn system on the market and allows you to separate each of the three Black trumpets from the mounting base – perfect for trucks and SUVs with limited mounting space.

Your Wolo Express Pro Train Horn includes a rugged Steel mounting base, which is finished in a Black powder coat. This base along with the 4 heavy-duty rubber bushings virtually eliminates road vibrations, even on the bumpiest of off-road excursions. Your included compressor features a heavy-duty 12V motor which has been factory balanced for absolute precision. A pressure switch, manual water drain, pressure gauge, and pressure relief valve are all fully integrated.

Each kit contains everything you’ll need for a complete and professional installation. That includes an onboard air system capable of producing the high pressure needed to blast out a blaring sound. An extended-length Stainless Steel high-pressure hose connects your compressor to the included 2.5-gallon storage tank. Mounting hardware, high-quality brass fittings, and 10' of flexible high-pressure hose are also included. Backed by a 1-Year Warranty.
