After everyone's glowing responses about 6000K I have decided to change my stock HID bulbs to phillips 6000k. One question though, I was looking at my bulbs and there seems to be a cover around the bulb with an opening on top for the light to reflect (stock set-up). Therefore, my xenons appear to only fill the upper portion of the entire headlight. (by headlight, I mean the entire polycarbonate casing) Is this normal? The pictures people send in seem to have light in the entire headlight.

 

this is normal, this is the d2r setup. the lower portion of the bulbs are covered up so it doesn't reflect light up into the sky. when you take pics things might look different. but if you look at stock hid housing, it's always just the upper portion lighting up
