Hey everyone i just let go of my 1999CLK430 and upgraded to a 2002 c32, and i must say.. i absolutely love it! but i was just wondering, what kind of headlight bulbs do they use? I have the xenons but i'm looking to upgrade everything to blue: the foglights, the city light bulb, and possibly upgrading the headlight bulb to something more blue. Also is it tricky to install them myself? i did them on my old car but these seem different..thanks!
