How do you replace tail light bulb on a 1998 Kia Sephia?
You have to remove the tail light first, and to do this you have to take the 3 screws on the tail light, open the trunk, remove the 3 screw and pull the light toward the outside (slide it to the side, if you are taking the left taillight out slide the tail light toward the left, if you are doing the right side slide it toward the right side).
Change the bulbs, and install on the reverse.
