NC warning light--what does this mean.

Have got a flashing red light on the oil pressure gauge. Car shape.

Only on when ignition is off , as soon as engine is started light goes off.

Oil level is fine.

Immobiliser light , it sounds like it’s working as it should

Never noticed it before---old age strikes.

Thanks.
