I thought that looked like a bell...so when you ride:: "Everytime a bell rings,an Angel gets his wings"!!! (From,, It's a Wonderful Life,,,a old movie)I've got a guardian bell on my bike. Guardian® Bell manufacturers of the Guardian® Bell, made in the USA First thing that got put on it the day I brought it home. My Dad picked it up for me. He told me I'm not to ever ride without it. More of a Harley guy thing. But pretty cool. Actually can get a little emotional when someone gives you one. Shows they truly care.
