Hi not sure if my headlights are standard or not but the bulb has gone on my drivers side headlight. I have managed to remove the assembly shown here:

I can't seem to pull the bulb out, does anyone know if I can replace just the bulb (and if so what part number or what am I looking for at halfords) or if I need to go to BMW for the full assembly? If I need the full assembly is it number 15 on this diagram (looks different to mine)
