Review on VEVOR 150DB Train Horns Kit - 4 Trumpet Air Horns with 120 PSI 12V Air Compressor and Tank, Super Loud for Trucks, Cars, Jeeps, SUVs (Black) by Lawrence Allison

These are small horns so they are high. (I knew that when I bought it) The horns will be retrofitted later. But holy please. If you order them, you will get the best shipping option, otherwise it might get lost on the way. It took 3 weeks to receive mine after they sent out 2 replacements? I can't remember now, I actually gave up and just waited for the (back) option to appear again. But overall the horns and compressor were exactly what I wanted at the moment. (Edit) Buy a better quality solenoid. After a few uses, the original barely holds the full 125psi pressure, isn't strong enough to open, or may get stuck in the open position. Overall, the Compressor did not disappoint.
