Wing mirrors is easy - fold forward the mirror a little but and you will uncover a small torx head screw holding the little light unit in place - unscrew and prise out.
I was going to change mine to whiter bulbs but noticed one wasnt working - even when I put a new bulb in so the dealer is going to be looking into that.
Sidelights in the headlights depends if you have Xenons or not as the unit is different.
