ok i think this is wat u need.. correct me if i'm wrong.. now if u want a direct replacement for ur lowbeams tthe size is H7.. this is also the size on the facelifted models. now refering to the wattage and the colour temperature.. if u get mtec bulbs go 50w as 100w will burn out ur terminal as ken said.. this is coz ur stock bulbs are also 50w.. colour temperature (the 4350k thing) is a scale.. the lower the number the yellower the colour emitted. the higher the number the more whiter, then bluer the light (until bout 12000k where it gets to purple).. now 4350k is quite white.. if u want a blue tinge go towards 5000k.. higher colour temps do not melt the terminals as it is not a measure of heat, its just a colour scale.. also the higher the number, the more ur vision will reduced at night.. btw.. foggies are H1 and rear licence plate lights are same as parkers T10 i think. i hope that helps.. andy
