How do I change the sound of my car's horn?

We may not be able to change our singing voice (sorry, karaoke fans) but we can alter the voice of our car or truck. Vehicular horns are a piece of safety equipment, intended to warn another driver or an errant pedestrian of an imminent collision or other danger. While there are also certainly times that they’re used to indicate our displeasure, They can also say, with a quick double-tap, a less-threatening “you may proceed” or even “goodbye!”
