Correct answer
It is normal behaviour and is not warning of a charging-system fault.
That is normal behaviour: the lamp is not warning of a charging-system fault. It does not by itself prove that every electrical component is healthy or that the battery is fully charged. If it lights with the engine running, there may be a fault in the alternator, regulator or electrical installation; follow the manufacturer’s procedure. If it fails to light when expected with the ignition on, its remaining off must not be treated as proof of correct operation.
