Review on 🚂 FARBIN 12V Blue Air Horn Kit for Car and Trucks with Relay Harness, Switch Button – Loudest Train Horn for Enhanced Sound Experience by John Mejia

Cheap plastic, poor fit and finish but this horn does the job. I installed it with my factory horns, not as a replacement. Insanely loud and fun to watch people's reactions on the road. 4 stars because it was very cheap and works exactly as advertised. This is definitely a Chinese gray market product. There is no mark on the box. The instructions are on the outside of the box and are difficult to read, save yourself the hassle and find some installation videos for similar products on YouTube. A word of caution, this thing is poorly made so install it where it won't get wet; mine is opposite the firewall, where it stays nice and dry.
