That light socket is just pushed into that mount ,pull it out and glass bead ,wire wheel or sand the bracket and paint them dull silver and they will look like new . If you look under the bottom of the dash you will see where they were bolted
One time when we were doing a photo shoot, we installed 1156 bulbs in those sockets. They really lit everything up. But we only left them in for about 30 seconds for fear that we would melt the wiring.
