How do you replace the front and rear side marker lights on a Lexus IS 300?

To replace the front and rear side marker lights on a Lexus IS 300, first, ensure the vehicle is turned off and the parking lights are off. For the front side markers, gently pull the light assembly out from the fender and twist the bulb socket counterclockwise to remove it. Replace the old bulb with a new one, reinsert the socket, and push the assembly back into place. For the rear side markers, access them by removing the screws or clips securing the light assembly, then follow the same bulb replacement steps.
