bulbs may take time to burn in. has nothing to do with factory ballast since they are only 35 watts. 55watts would wash out the colorI bought replacement 10k bulbs from DDM and they look more like 8k I was going to buy the 12k from them but then i was thinking is it the factory ballast that it is not putting out the power to light the bulb to the blue color.
As a matter of fact, 4300k has the highest visibility. I don't like the color as much as my current setup, 6000k's with my projector retrofit and 3000k hid fogs. The setup I have turns heads with the projectors though imo. I see for miles down a road hahatheoretically speaking the 4300k is brightest, but I will have to say I have better visibility with my 6000k setup. Maybe I see the white better on the road or I am just bias
