so i was just about to order PIAA Xtreme white plus bulbs when i ran into a problem. from thetirerack.com (http://www.tirerack.com/accessories/...null&x=58&y=11)
they have only one product listed and it seems like it comes with both high and low beams. but upon further inspecting at performanceproducts.com (http://www.performanceproducts.com/P...producttype=10)
they have low beams, high beams, and headlight bulbs listed. which ones are the correct ones and which ones will work/do i need for my car? thanks for the help.

edit - i just noticed this as well, it seems that H7 and 9007 are different bulbs, should i just get them from thetirerack.com since they have H7 designated?

H7 and 9007 are VERY different bulbs. H7 is for high and low beams and the fog lights are 9006. $75-$80 for H7's = LOL OMFG NO WAY. You should take a look at Sylvania Silverstar bulbs. $38 for a pair at Walmart, they look great.

yup he's right.
... i got piaa now for all (including foglights) , i used to have silverstar on lowbeam.

hmmm, ok, thanks for the replies, why performance products doesn't link to ANY H7 bulbs is beyond me when you select the car as being a C230 Kompressor. thanks for the info, guess i'll be ordering from performance products then, i may just go ahead and pick up a pair of SilverStars as well since they're so cheap and just compare them to see which ones i like better

how would you rate the PIAA compared to silverstars? which ones do you think look brighter and which do you think are whiter or give a more HID look?
