Customer Question

Hello - I bought a GE 2.4 m / 8 ft Winterberry pre-lit tree from Costco. Just this evening, the whole tree started flashing. I had it plugged into a surge protector. I turned that on and off. I tried plugging it into the wall. I tried another outlet. It still flashes. I couldn't find anything in the instructions that came with it that give me a clue as to what is going on? Can you help, please?

Hi there!

Check every bulb (yes, all 504 of them!) in case any of them are loose.

If just one bulb is loose in its socket, it may connect intermittently and cause the other bulbs to flash off and on.
