This is a 4 trumpet train horn kit for car, truck, UTV, off-road vehicle or even build your own DIY Impact Train Horn. Comes with horn mounting bracket and hardware, compressor mounting hardware, 12 volt mini air compressor, tubing and 4 trumpet train horn. These are extremely loud 140-150 db.

They can also be used for a impact drill train horn setup. Picture is shown of a completed impact drill train horn. This is for reference only and does not come with the set. You will only receive the horn, compressor, tubing and brackets as mentioned above. I use this exact kit to build Dewalt, Ryobi, Milwaukee and many other horns.

Very good product, very reliable. Sold over 1000 of these last year alone.
