From the 'gadgets for bikes' spot.

If you're older you probably recognize this as a clown horm. It's also called a Bugle Retro Horn Yes, it looks like those retro clown horns, but this classic vintage metal twist hooter is a good way to let people know you're coming without scaring them with a high decibel electric horn. Plus it doesn't require batteries & there's nothing to charge. It use plain old free air found everywhere. Just squeeze the rubber ball to sound the horn. Easy to install on the handlebars of a bike, scooter, etc. I have an older friend who has one on his scooter and not only do people step out of the way, they often laugh & say something like 'great horn!' Available in colors, but I like red the best. Under $10 as of 12/25/19 on Amazon, but Amazon prices can change at any time.
