My ex-son-in-law had a train horn on his truck, and I almost wet my pants the first time he used it on an unsuspecting motorist!
I haven’t tried the horn out on Mr. Bill. I haven’t really had occasion to. Right now I’m concentrating on things to protect it from the desert sun. I may have to invest in a car cover, because the windows are so hugh.
Tomorrow, I will take it to the car wash and see how it runs when wet! LOL!
