How do you change the third brake light bulb in a 2010 sonata?

To change the third brake light bulb in a 2010 Hyundai Sonata, first, open the trunk and locate the access panel on the rear deck where the light is situated. Remove the access panel by unscrewing any screws or pulling it off gently. Then, twist the bulb socket counterclockwise to remove it, replace the burnt bulb with a new one, and reassemble everything by reversing the steps. Ensure the new bulb is securely in place before closing the access panel.
