Disconnect the negative cable from the battery. For sealed beam type, remove the radiator grille, then take out the headlight retainer screws while ensuring the adjustment screws remain undisturbed. Remove the retainer and pull the headlight out for access, unplugging the connector. After removing the headlight, plug in the connector securely, position the headlight, and install the retainer and screws, tightening them securely before reinstalling the radiator grille. For halogen bulb type, open the hood and reach behind the headlight assembly to grasp the bulb holder, turning it counterclockwise to remove it. Lift the holder assembly out for access to the bulb by unscrewing the collar and withdrawing the bulb holder from the housing. Press the release clip and pull the bulb assembly out of the connector, holding the clip down to unplug it from the bulb holder. Insert the new bulb into the holder and seat it properly before installing the bulb holder back in the headlight assembly.
