Both my headlights have stopped working.

My 2012 mazda cx7 is doing the same thing, checked relay its ok fuses ok.Anyone have an answer??I wouldn't think it could be the stalk switch as we always leave lights on auto. Both headlights were replaced about a month ago??Love this car but these headlights are a pain to replace.You have to rake the car apart and go through the wheel well.Zoom zoom, Mazda. Any ideas appreciated,gonna try the bulb again just to be sure,but ridiculous that both would burn out together.
