Hi, I looked online and keep getting different answers and I really do not want to order wrong bulbs. I am going to order some DDM Tuning hid kits and i need to know the bulb sizes for low beam and fog lights. I am 99% sure that low beam is H7 (my car didnt come with stock HID), but I am not sure what size for the fog lights?

Stock low beam is H1. Stock high beam is H7. Stock fog is H3.
