for those of you who have either one, how's the brightness at night?
for those of you who have seen both on them side by side(2 cars), which one is produce more light output and better vision at night?
for those of you who purchased either one, how much is a fair price?
On ebay, the 6000k philips is 425, and the K2 is 450.
