for the cool looking sake, u can use 7500K PIAA bulbs...they do great,
but kindly reminder, the higher the color temperature goes, the lower the visibility you get.
yea, everything seems bluer but darker if u drive with bluish bulbs...
factory HID outputs 4000~5000K of color temperature. Which gives the whitish color and best visibility.
