Thank you. I was pretty sure that AC/DC converter was an extra item, but I thought I would ask you to confirm my suspicions.

I hope to receive my LED headlight bulb this week. If this LED bulb works as well as expected, I certainly plan to order more bulbs for my other motorcycles from the Taobao link you provided.
