Our low beam lights quit working without warning. Sometimes they come back on at other times they do not and you have to hit the high beams or even the fog lights. Not a good thing to happen. Car is always in motion at night when failure happens. This has happened many times over last couple of years. Not sure how many times. Not always noticeable depending on if you are in city lighting or in country. Daylight running lights, high beams and fog lights seem to work but not low beams.
