im assuming your talking about the lights that are at the bottom of the driver and passenger side door. its very simple to do, i did both of them in less than 5 minutes. all you have to is get a flat head screw driver, and pry the upper four corners and it should pop off. be careful though, because there is a clip inside the could break. i would suggest doing it when it is on the warmer side outside, because the cold can cause them to become brittle and break. hope this helps. if you need anything else feel free to ask.
