To change the tail lights on a Lexus IS300, start by opening the trunk and locating the access panel behind the tail light assembly. Remove the screws or clips securing the panel and carefully pull it away to expose the tail light bulbs. Twist the socket counterclockwise to remove the old bulb and replace it with a new one, ensuring it’s securely in place. Finally, reassemble the access panel and test the new tail lights to ensure they function correctly.
