A case of having low oil would not trigger the light on by itself. A different symbol on the dashboard serves as a warning for low oil. It is usually an outline of a traditional oil can with oil dripping out its mouth. However, there is a chance that constant and prolonged low oil pressure can trigger the light. It's only the case if parts of the engine were damaged, such as a faulty oil pump or fuel injector. If it’s only low oil and there’s no damage, the light will not turn on.
