It depends on which bulb is burnt out. If it is the front bulb in the bumper you can reach up behind the bumper and unplug the socket and replace the bulb. You may need to loosen the valance to reach up to the bulb.
If it is the bulb in the front side marker just take out the screws and remove the fixture, the socket can then be removed to change that bulb.
If it is a rear bulb in a sedan or coupe:
1. Inside the trunk near the quarter panel on the side the bulb is burned out on there are three nuts. Remove the middle nut, it should be in the middle of the tail light fixture.
2 Pull the stud out of the body then pull gently away from the center to remove a tab from the backup light fixture. The fixture should now be loose.
3. Remove the appropriate socket and replace the bulb.
Reverse the procedure to reinstall the tail light fixture.
