And if it comes and goes, remember that the fail light only comes on when an exterior lamp fails to light when it should. What I mean is, if say, a headlamp it bad, the light will only be on when the headlights are on.



BUT, if you step on the brake and a brake light does not work, the light will STAY ON UNTIL THE KEY IS TURNED OFF. It will then light the next time you step on the brake.



I had a time wondering why my "light out" indicator would come on at times, then not at other times. Then I happened to realize it was the driver's side brake light. But MOST of the time, you can figure out what it is by turning all lights off, it should go out. THEN, slowly turn on various lights until the dash light comes on - the last thing you turned on, is, of course, the culprit.


I wonder if the back up lights or turn signals will light it?
