slow

the color temp (5000K, 10000K, etc) determines how blue. 3000K is yellow, 5000K is basically pure white, 12000K is UBER blueish looking (screams po-po come get me)...
if you're running H-4s (Protege sedan headlights) you'll need a bi-xenon kit to have HID lows and highs.... basically its just a solenoid in the bulb that moves the HID from the low beam focal point to the high beam focal point... fairly effective though.
