How do I adjust The headlights on a Peugeot 307?

you cant unfortunately, but if you google valio headlights there is a dealer in Devon who will supply two new lights complete with bulbs etc for the price of one from Peugeot. Peugout wanted £150 for drivers side headlight. Here is the link

Pain in the bum to buy new ones but they are OE kit and are the same as on your car but lenses are obviously different
