To replace the headlight bulb on a 2004 Chevrolet Trailblazer, first, open the hood and locate the headlight assembly. Remove the plastic cover or clip securing the headlight if necessary, then twist the bulb socket counterclockwise to release it. Pull out the old bulb and insert the new one, ensuring not to touch the glass with your fingers. Finally, reassemble the socket and cover before testing the new bulb.
