How do you change a side light for a Ford Fusion?

To change a side light on a Ford Fusion, first, ensure the vehicle is turned off and the keys are removed. Open the hood and locate the headlight assembly; depending on the model year, you may need to remove a cover or twist the bulb socket counterclockwise to access the bulb. Carefully pull out the old bulb and replace it with a new one, making sure not to touch the glass part of the bulb with your fingers. Reassemble any covers and test the new light to ensure it's working properly.
