How do you change a bulb on a corsa for the odometer?

To change the odometer bulb on a Corsa, first, ensure the vehicle is turned off and disconnect the battery for safety. Remove the instrument cluster by unscrewing the necessary fasteners and gently pulling it out. Locate the odometer bulb socket at the back of the cluster, twist it to release, and replace the old bulb with a new one. Reassemble the cluster and reconnect the battery before testing the new bulb.
