How do I adjust the headlight beam on a peugeot 306?

Behind the light inside the bonnet is a black plastic cover. Turn it clockwise (while looking from the front of the car). This will expose the connections behind the lights. Pull out the blck socket / connection. Theres a clip holding the light in place and its a bit tricky to get off! At the top of the clip, you need to push the clip hard to the left to resease the clip and then you can move it down. Pull the old bulb out and then replace with the new one being careful not to touch the actual glass of the bulb. Reconnect in reverse. Hope this helps. Kate
