United Pacific 46151 Competition Series 3 Trumpet Train Horn, Heavy-Duty Electric Solenoid, 150 PSI Max, Super Loud Output 150dB +/- 10 dB - ONE Set

Perfecta y buena calidad

Added to my semi with 3/8 air line instead of the 1/4 line that came with it. Sounds amazing.

they sound great. fairly simple to install if you get all the right components. you need to get a compressor and tank. i tried to stay small with a 1.5 gallon at first but realized its much more logical to go to 5 gallon. Id say at least 3 gallon just so the compressor is not running all the time if youre planning to use them often or in long bursts when playing around with buddies. The tone is maybe a tad bit higher pitched than a freight locomotive but nothing even noticeable. if you were near tracks and heard these with a good blast you wouldnt know the difference.install is fairly simple i wired mine into my switch panel for emergency lights and led floods in my truck and put the tank and compressor in the toolbox. with a little wiring knowledge and some basic tools its an easy install in a couple hours. i also added a t with a fitting to run an air hose for pumping tires, dust gun, and other small air tools.overall definitely a great bang for your buck

The media could not be loaded.  Great product for the money. Easy installation. Definitely recommend over high dollar train horns

The media could not be loaded.  these things are stupid loud

Just arrived. They are very well put together. Nice chrome finish. No quality issues. Test fired them with an air compressor and they are stupid loud. Can't wait to fit them on my dually

Diaphragms blew in a few blows at 140psi but I put a regulator on at 120 and they seem fine after that.

Sounded good but did not last one month:[

Funny looking trumpet. 🤷‍♂️
