To change the side indicator bulb on a Vauxhall Corsa, first, ensure the vehicle is turned off and the keys are removed. Locate the indicator light assembly, typically found on the front fender or rear light cluster. Gently twist or unclip the assembly to access the bulb holder, then remove the old bulb by pulling it straight out. Insert the new bulb, ensuring it's securely in place, and reassemble the indicator light assembly before testing the new bulb.
