Personally, I can't see anything with the "ultra white" and "blue" lights. I actually bought some Luminics Ultra Golden H4

They seem really yellow up close, but at a distance it is (at least for me) the perfect color. I can see details and contrasts in the road really well. If you look at the color temperature, they are between XtraVision and Silverstar.
