Review on Loud and Powerful: Vixen Horns Train Horn with 4 Air Horn Black 📢 Trumpets for 12v Vehicles - Perfect for Trucks, Cars, Semis, Pickups, Jeeps, RVs, SUVs (VXH4124B) by Todd Vesci

***Video update added. I didn't want to upset my neighbors so after installing it in my truck I drove a half mile in a straight line to piss off other people I don't live near. Ignore what you see on the video, my girlfriend stood in front of my house and used the video to record me with beeps. Once again I was half a mile away and my air system was running at 120psi. I hope this helps someone decide if they should buy this ***. The noise level and tone of these horns met my expectations. I took another reviewer's suggestion and replaced all 1/2 inch hoses, fittings and replaced the electromagnet as soon as I received them. I don't even know how they sounded with the tiny airline and associated fittings, but I can tell you that thing is LOUD with the 1/2 inch plumbing running down! It has the sound of a real train. I know because I usually hear one of them around my house twice a day. I'm sure my neighbors will be thrilled that I'm testing horns in my garage. I don't use the horn on my truck very often, but now that I do, the person knows exactly how happy I am with their driving! I can't wait for the first idiot to do something in front of me.
