brian, looks like your bulb is "whiter" than don's
Neal, I've not been able to confirm the color temp on the Harley branded HID headlight. Have so far seen it referenced or been told it was, alternatively, 4250k, 5000k, 6000k and 7250k.
I know for sure that the blue on the new ones I installed are BLUE. And they stay blue shining all the way down the road. Some HIDs on cages I've driven started out bluer and then faded back some as they got warm. These things start blue and stay that way.
It was actually a bit eerie to get used to for the first few miles. It's an unusual caste of light to look in to. Once you learn that you can trust you begin to realize that contrast and other highlights within the beam are actually very very good. From every visual comparison I've run cross so far though these new lights are a true 8000k blue. So now matter which of the several options for the Harley light might actually be correct it won't look as blue as do these new lights in the red bike.
The company I got them from offer their kits in several color temps actually. Several temps less blue and down through the white and gray ranges "lower" than what I chose and a purple hued HID bulb with a color temp "higher" than what I chose. They all were represented as casting their light roughly equally down the road. So that color doesn't seem to directly represent the effectiveness. I just liked the blue color....
