How do you replace rear side marker?

To replace a rear side marker light, first, ensure the vehicle is turned off and the key is removed. Locate the side marker light assembly, usually found near the rear of the vehicle; you may need to access it from inside the trunk or wheel well. Remove any screws or clips holding the assembly in place, then gently pull it out. Replace the old bulb with a new one, reassemble the marker light, and test to ensure it's functioning properly.
