Best way and to keep the skin on youre knuckles, is to take the front wheel off on the side of the car that needs the headlight to replace,then take the splashguard (plastic liner) from the wheel arch there are a couple of bolts and plastic clips to undo, pull the liner out "bit of a fiddle".When you have done this you can see the back of the dust/mud cover of the light assembly, lift the clip up out of the way then take the cover off by lifting it up then you will see the bulbs, pull the conector off the back of the faulty bulb and replace with new one, make sure you use disposable glove's not to leave a finger print on the bulb other wise you will be doing this sooner than you need as the oil from youre skin will leave a hot spot on the bulb and it will burn out,then put back in the same order as you took off.
