Hi, I'm Mike G and I'll be assisting you. Flickering is the sign of a bad connection. It may be in your panel if all outlets are showing flickering or it may be a utility problem ahead of your service. If you have a 2 wire voltage tester, I can instruct you on determining which it is and if it is in your panel, how to correct it.
Very good, thanks for letting me know.
