    Summary: I customized my car horn to play three different sounds. The main sound is the "Courtesy Honk" which is used to get the attention of other drivers in a non-emergency scenario. It's two quick chirps of the horn that is not only friendly sounding, but it's not as loud as a normal car horn. PLEASE CONSIDER SUBSCRIBING:

    Ok, let me just say that this is a really cool idea. Mark you should make a business out of this, I bet a lot of people would love to have a feature like this in their car but dont have the skills or knowledge to put it in themselves. I bet you could easily sell an idea like this to a car company and they can implement it somehow in their new car models. This may have been an idea you made just for fun, but that's how entrepreneurs are made, from the simplest things they made or thought of.

    "This will never happen to me"... Famous last words... Atlanta drivers will not accept any horn as "courteous"... I've actually seen shopping carts thrown through the windshield of a car with a train horn... Be safe !

    To be a true Canadian, your horn would have to say "sorry eh". Get on that

    The normal horn was originally introduced to identify danger, and now people abuse it. What's to stop the same happening with this horn?
