My whole adult life I had wanted a full-size truck.  A big, imposing truck painted fire-engine red!  I had to wait until I was 40, but I finally got it.  In my opinion, a huge truck needed a blasting horn.  These puny, little “beeps” that come factory standard would not do!  I found an awesome company that sells train horns for cars.  This is an amazing sound!  No one misses it when I honk.  It’s cool to watch people scramble when they hear me coming.  They are never quite sure what is coming at them.   My wife has accused me of acting immature, but I am loving every minute of it!
