what do I do about changing to a white light on my fog lamps ('01 SS) , it is just changing a bulb or more complicated?

 

Yup it is just changing the bulbs. Of course if you want something brighter, you have to change the whole housings. I have these on mine and look real nice with my HID like driving lights. Real cheap too.
