A good place to start is your fuses and then check the actual lights. I had that problem too, it might be the DRL module under the dash to the left of the ash tray. careful, its next to the airbag lines. it would be about the height of your right knee, if you seated in the drivers seat. a small metal box about 2"x2" dark brown or gray color with one wire plug in it. its kinda hard to get out and its not cheap.
