Don’t be fooled by their compact size; these horns will wake the dead. They sound with a very high-frequency blast that can only be described as banshee-like. Being lightweight and small in size they are the perfect match to any of our larger train horn kits.Use this product in a safe and responsible manner, at a distance of at least 100 feet from others.Proper Hearing protection must be worn when using this air horn. Hearing loss or permanent damage may result from unsafe use.Never operate this product in a closed environment or close to pedestrians or others.It is the consumer's responsibility to comply with local noise ordinances and D.O.T. sound level laws.
I'm very disappointed in this horn. It's nowhere near as loud as advertised and the longer the horn has been on the truck and each time I use it, the weaker the tone seems have gotten and the tone has changed to more of a squeal than a train horn. I'll be doing more research and uninstalling it soon.
