The low water level sensor is in your radiator overflow resivoir. The reservoir is supposed to have a certain amount of coolant in it but if it's low, the light comes on. This has nothing to do with the radiator being empty. True, if the reservoir is left unchecked the radiator may eventually become low and then you will overheat but until then, it's just telling you the reservoir is low.
