So can this kit (awesome by the way!) be fitted straight away to my facelift (07 plate) Fiesta

?
Does it work exactly the same as my 'normal' headlamps do now? I.e, same switch, main/high beam etc?
AND! Do the sidelights stay the same or will they need replacing? I don't really want to do that because I've got some fantastic white/blue ones in at the minute! I'm guessing this kit is just for the headlights (main & dipped beam?)
Sorry for all the questions!!
