What gauge is the wire?

[rbkt65]

That is used in the light sockets that illuminate aftermarket gauges. It seems smaller than 22 gauge. Is it readily available anywhere? TIA.

If you have a section you can count the number of strands and then with a caliper measure the diameter of the strand.

There are charts online that will give you the gauge.

It's easier if you measure in mm

Regardless of the size in the pigtails/ sockets, I would not use anything smaller than 18, simply for physical strength
