To replace a bulb first, you have to open the hood. For early models, release the bulb retainer by turning counterclockwise at the back of the Headlamp then retract the bulb socket from the Headlamp housing. It is usually recommended that one should gently withdrawal the bulb ways from the socket without applying any twist on it and using hands to hold the glass part of the bulb. Place the terminal of the new bulb into the socket with the flat visible at the plastic based turned upward, align the locating tabs on the retaining socket over the notches on the Headlamp housing and secure this by applying pressure to force the socket's mounting flange to engage the housing. Place the retainer on and force it clockwise up to snug stage. As done in the later models, the Headlamp assembly should be unscrewed, the bulb socket should be rotated clockwise then you pull it out. When removing the bulb, one has to be very cautious and gentle to pull it out straight from the socket while the process of installation is vice versa. Once the bulb is replaced perform operation check of the entire Headlamp and close the car hood. Any alignment of the Headlamp should be checked and ought to be adjusted by a dealer service department or a service station at the earliest occasion. For removal of the housing and its installation in the early models first remove the bulb and the wiring of the housing followed by the removal of the clips that hold the housing in position as it is taken out from the grille opening panel. In latter models you should release the Headlamp housing retainers, pop out the Headlamp and remove the electrical connectors. Removal is the reverse of installation and it is advised to check the Headlamp alignment.
