Review on 🚗 MKING Car Horn Motorcycle Horn Electric Loud 12V Super Tone - Double Truck Train Horns Waterproof - Air Horn Raging Sound 120DB for Car Motorcycle Trucks, Red by Jerry Frey

The standard horn on my bike is around 100 dB and can hardly be heard on the motorway. This is measured at 120 dB. I only used one horn, so that's a lot. The sound is pretty harsh and raspy, but it's a horn so I don't care. The construction is metal and comes with a nice bracket. Just note that it may be larger than the stock horn.
