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.
Those look like press-ins, and they’re pretty standard. You could remove the bulb itself like mentioned, or you can remove the whole piece from another set and just press them into yours. I don’t know if you’ll be able to find individual lights though.
