How do you change a headlight bulb on Fiat Ducato?

To change a headlight bulb on a Fiat Ducato, first, ensure the vehicle is turned off and the keys are removed. Open the bonnet and locate the back of the headlight assembly. Depending on the model, you may need to remove a cover or release clips to access the bulb. Carefully disconnect the old bulb, replace it with a new one (making sure not to touch the glass with your fingers), and reassemble everything securely before testing the new bulb.
