For fog lights, 2018 and later Sequoia and some Tundra models utilize LED fog lights that are not serviceable; if an issue arises, the entire assembly must be replaced. For halogen bulbs, disconnect the electrical connector, turn the bulb holder counterclockwise to remove it, and pull the bulb straight out for replacement, reversing the process for installation.
