Front headlight bulbs?
 

I know i will probably get flame for asking this since its likely to be in the owner's manual guide booklet but i am at work right now so i cant take a look at that. I have some free time right now and would like to look up some after market bulbs and was wondering what size or kind of bulbs will fit a 2008 bmw 528i? I will like to put some 6600k for the low beam. Thanks,

Check out stealthauto.com, i bought my AE bulbs from them as well as new sidemarkers and turn signal bulbs.

Are we to assume that you don't have adaptive headlights?

I'm guessing he does since he's asking about 6600k bulbs in the low beam.
