How do you replace BMW Z3 headlight bulb?

To replace the headlight bulb on a BMW Z3, first, ensure the car is turned off and the keys are removed. Open the hood and locate the headlight assembly; for easier access, you may need to remove the cover or the entire headlight unit. Disconnect the electrical connector from the old bulb, twist the bulb socket counterclockwise to release it, and replace it with a new bulb, ensuring not to touch the glass with your fingers. Finally, reassemble any parts you removed and test the new bulb before closing the hood.
