Yeh, I don't think alot of OEM owners know that, and end up driving with less visibility over time. That's why so many OEM set-ups look 6000k; it's because they have shifted from 4300k towards 6000k if not possibly beyond.
hey i just went back to halogens tonight, and i must say they cover about just as much surface as my HIDs did, but everything is not blue, and i cant see signs as well, and they look a fairly sad yellow. i dont see what how cars like the 300c and newer cars have a purely white color while i get the ding looking color.
