Review on 🚂 150DB Air Train Horn Kit for Car, Loud Twin Tone Chrome Plated Zinc Dual Trumpet with Compressor – Ideal for 12V Trucks, Lorries, Trains, Vans, Boats (Silver) by Seth Gomez

I initially connected it and it didn't work, I looked at the instructions and everything was perfect. Then I read the reviews and it said to connect the white wire to the red hot wire for my separate button and ground the other side of the button. I also had to switch the connections on the compressor because I put them in the back which pushed the air out of the compressor but not through the whole place where the hose connects. Not as loud as I thought but safe to get someone's attention if needed. I love this horn!
