Low beam lights not coming on,2006 Mazda 3. Why?

The same bulb in a lot of applications controls both the high and low beam. Generally the low beam portion will burn out and for a short time you will be able to use the high beam only. I can't be certain which headlight switch that you checked, but the most common solution is to replace the headlight bulb.
