Thanks for your responses. Stay tuned for the next what the heck is this and what does it do question on my bike! And as for the gremlin bells, I'm surprised nobody gave me a hard time about one of them having a HD logo on it but then you probably couldn't see it! It was a gift and I liked the skull outlined in crystals on the other side of it so I figured I could forgive the HD logo especially since it would be under the bike.
