Review on 🚗 FARBIN 12V Mini Air Horn, Loud Car Horn with Chrome Zinc Dual Trumpet, Compressor Wire Harness and Button for Trucks, Cars, SUVs, RVs, Motorcycles, Off Road - Mini Version with Button by Brett Morrison

After hours of trying to figure out the damn relay and a night's sleep. I was able to get it working. I used to have a compressor horn, a tank horn and a slide horn. It doesn't have enough power to press the train horn and "whistle", the sound is a bit cheesy. Yes it works. Instructions What are Instructions? I've never seen!
