How do you change indicator bulb on astra hatch?

To change the indicator bulb on an Astra hatch, first, ensure the vehicle is off and the keys are removed. Open the hood and locate the headlight assembly for the side where the bulb needs replacing. Remove the protective cover or twist the bulb socket counterclockwise to release it, then pull out the old bulb and insert the new one, ensuring it's secure. Finally, reassemble any covers and test the indicator to confirm it's working properly.
