And one minute before you click on the costly buy option, take a look at your US sealed beam headlight.
They come in three color temps: 3200, 3400, and 4000K. The latter are much better and to my non-refined taste, very bright. If satisfied, you've solved your problem for $20 plus shipping.
The Sylvania halogen model is Silverstar H5006 for the low beam and H5001 for the high.
(besides, US headlights look sooooo much better
