Does anyone know how to remove the wires from this light socket, does anyone know how I find information about this type of socket?
Why not just remove it at the terminal blocks visible in the background? You may have to pull them out of the wall.  

These are single-use "backstab" connections.  The wire can be removed either by firm pulling or jabbing a screwdriver in the slot release there, but then, the spring will be damaged and will no longer hold reliably. You would need to replace the socket at that point.
