Review on 🚛 2PCS 300db Train Horn for Trucks - Loud Air Electric Snail Single Horn - Waterproof Motorcycle Snail Horn - 12v Double Horn - Raging Sound for Car and Motorcycle by Joey Gilbert

The first thing I did was unpack the goods and found that there was no relay. When ordering, nothing was said about the need for a relay. I then connected both horns to the power supply according to the instructions and was very disappointed. The sound is not like a train whistle but more like a car. Very disappointed with the product.
