I have at least two #64 MTH street lights that do not work because the connection between the base of the light and the power wires is not tight. The way these worked is that there was a metal strip that put pressure on the wire and made the connection. You would take the power wires and slide them into place.
Now seems my metal strips do not hold with enough friction to keep the connection tight. So what I think I need are new metal strips or the entire plastic/metal base piece, see picture, or if not available a work around for this issue. Many thanks.
