How do you replace reverse light bulb on mini one?

To replace the reverse light bulb on a Mini One, first, open the trunk and locate the access panel behind the taillight assembly. Remove the screws or clips securing the panel, then gently pull it away to expose the back of the taillight. Twist the bulb holder counterclockwise to remove it, replace the old bulb with a new one, and reassemble everything by reversing the steps. Make sure to test the new bulb by engaging the reverse gear before closing the access panel.
