'35 Tailight electrical replacement...wire and connector

[HenryCarl]

I'm casting about today...

We, my friend and I, have concluded we need to replace the taillight socket for my 1935 Ford 5 window. While I’ve found the wired set to purchase (a couple with springs), how do we remove the old one and replace it? It seems glued in place or at least it baffles us.

Thank you.
