How do you change a backup light on a 2003 Pontiac Grand Am?

To change the backup light on a 2003 Pontiac Grand Am, first, open the trunk and locate the access panel behind the rear light assembly. Remove the panel by unscrewing or unclipping it, then detach the light bulb socket by turning it counterclockwise.
