Unfortunately, if you are referring to the door handle lights, you have to pull the door panel to get to them, pull back the foam pad above the door handle and pull the light harness out of the top of the handle assembly. I found replacement bulbs at pep boys. They're Sylvania #2721. Isn't too hard, just take your time... Good luck!
Oh, and BTW... Be careful when removing the plastic trim pieces on the door. They are very soft and can be scratched or break easily...
