With this unit, if the engine is switched on, no warning tone will be generated during the day or night. If the engine is switched off during daylight, this will start a warning tone which will stop when the driver switches off the lights. Should the driver stop at night and leave the lights on, again no warning will be generated, as leaving lights on at night is still necessary in poorly lit areas.
