The headlight bulb is covered by a rubber boot, peel that back. The bulb is held in the shell by a spring wire arrangement. press together the ends of the wire and hinge back in the direction of the rear of the car. The bulb has 3 location lugs and you have to fiddle around until the bulb can be removed from the shell. Pull the bulb from the electrical connection. Reverse procedure to refit, noting that the bulb has to go back in the correct position determine by the lug off-set arrangement.
