How do you replace a fog light assembly on a '05 highlander?

To replace the fog light assembly on a 2005 Highlander, start by removing the screws or clips securing the fog light cover under the front bumper. Once the cover is off, disconnect the wiring harness from the old fog light and unscrew the assembly from its mounting bracket. Install the new fog light by securing it in place, reconnecting the wiring harness, and replacing the cover. Finally, test the new fog light to ensure it works properly.
