How do you change a indicator bulb on a peugeot 307?

To change an indicator bulb on a Peugeot 307, first, ensure the vehicle is turned off and the key is removed from the ignition. Open the relevant side's door and locate the indicator light assembly; you may need to access it from the wheel arch or under the hood depending on the model. Remove the bulb holder by twisting it counterclockwise, then pull out the old bulb and replace it with a new one, making sure it's securely fitted. Finally, reinsert the bulb holder and test the indicator to ensure it’s working properly.
