Dearest lemmings, I have a prelit Costco tree that changes from warm white to color and several of the lights are out but I cannot for my life find a replacement anywhere. I called Costco/Polygroup (company that made the tree) and they don’t sell replacement led light bulbs but they gave me these specs: LED dual color 3mm Green Base 20MA 1.8-2.4V or 2.8-3.6V. I tried buying a set of lights at Home Depot but they did not fit and my google-fu is failing me.
If you can’t replace the bulbs, could you buy a new string with similar features and run it through the same pattern as the old string?
