Where can I find replacement plastic cover rings for 5-light xenon task and accent light kits made by Hampton Bay? The number on the front of the package is 148 120. Also, how much are they and can I obtain them locally (Strongsville, Ohio - near Clevelan) or can I order them to be shipped to me?

Call the manufacturer if you don't have anything with the number on it, call the store where you bought the item and ask them for the phone number.
Sometimes the manufacturer will send you replacement items at no cost.
