My guess is that they are the switched B+ for the gauge illumination. The bulb socket is the opaque piece. One half contact the brass strip that is ground post via the stainless steel strap and threaded stud. The other half of the socket would be connected to those blue wires. They will daisy-chain from one gauge to the others.
