Review on Vixen Horns Train Horn for Trucks and Cars | 3 Chrome Plated Trumpets | High dB Output | Compatible with 12v Semi Trucks, Pickups, Jeeps, RVs, SUVs | Model: VXH3114LC by Thomas Landis

Incredibly loud, although not as quiet as I had hoped. The tubes unscrew from the diaphragms and I removed the 12v solenoid. I fed them through a manual push button valve and used them as part of the front float! My only complaint is that the mount doesn't match the weight of these horns. I used a stainless steel machine screw and drilled a hole in the longest horn's bell to keep it from bouncing. It might be ok due to wind or being attached to a strong car frame but I would still worry about it breaking. I had an 11 gallon air tank filled to 100psi and no onboard compressor. I got a lot of use out of these horns on parade day and the tank was still about 80psi when I parked it. That was cool! (Pun)
