FARBIN Car Air Horn Truck Train Horn Loud 12V Car Horn Kit with Relay Harness and Switch Button

Excellent horn, very loud. Love this horn.

Install takes some Napa know how but better than moto horn

This is my 2nd vehicle which I add this type of horn. First was a Bad Boy and now this one, the Farbin. This is a fraction of the price of the Bad Boy, AND, it comes with all the wiring and relay, so much better deal. They both sound pretty similar, so really no justification to pay more. Installation took a while given the tight spaces and the difficulty to thread the button wire from the inside to the engine bay. Nothing related to the horn itself. But I did find the manual lacking in details and photos. Had to research and analyze it for a while (I'm not a pro installer nor an electrical engineer). So there's definitely room for improvement in the installation instructions space.

We actually purchased 2 different horns (this one and another from a different vendor) and we can attest that this one is indeed loud enough ( a lot louder than a car horn, but not a real life train horn), the other one we purchased was similar to a regular car horn in regards to the decibels, although it was being advertised as a train horn. This FARBIN horn will definitely make people notice you and/or get out of the way, what makes this one louder than the other one we bought, is that this one is an Air horn. Now, just to ensure that no one is misled by this review, I would like to add that we have a friend who had a set of 3 "train-hornblasters" professionally installed and you can not be standing next to his vehicle when those are triggered (but he paid quite a bit of money for those). So, although this FARBIN "train-sounding" horn is fairly loud, it is not at the same level of our friend's. Nonetheless, for the cost, it is a bargain that you can't pass and will not be disappointed. That is why we are giving it 5 starts and it is a keeper for us (we will update this review to see if it stands the test of time).

This horn was very easy to install because my WOLO horn died and everything else was already in place. It’s much louder and will get the attention of idiots quickly. Much louder than the weak horns that Harley Davidson installed. I’m very happy.
