Stay away from White vision ultra, do not buy them for any reason, low brightness, White vision is much better. I have tried both

WhiteVision Ultra H7 Halogen 4200K Natural White 12V 55W 2pcs

They are a little brighter and a little whiter, but don't expect them to be LED-like. No comparison.

Today I put them into operation and there was only driving in the city.
Their color is relatively white, of course they do not have the color of LED or xenon, but they are not the classic "yellow".
What bothered me is that their intensity is not strong as I expected.
They have a good beam and do not blind the opposite.
Easy installation as they are like regular bulbs, just when placing them do not touch the glass (as stated in the instructions of course).
What surprised me is that the package also provides T10 bulbs commonly known as fleas, which are in a completely blue shade and I believe that in cars where they have the same space, the headlights will have a different shade and both together.
Now, regarding the price, since they are not so powerful and have a relatively short lifespan, they should have had a lower price.
Will I buy them again??
I hope that something else will come out on the market so that I can try them, but if they have a lower price then I will prefer them again.

Pleasant to the eye the color of white, it deviates from the classic yellow and tends towards xenon without, however, this annoying shade and intensity. I would have liked them a little stronger in lighting, as coming from the xtreme vision I immediately noticed their lower intensity. No comparison, however, with a simple bulb. The lifespan of 200 hours seems very short, judging by how long the 400-hour xtreme lasted, but only time will show their durability. For the shade of white alone, I might prefer them again, although I would like to try the racing vision as well.

Very good light combined with the 4200K, the result is very good, the only negative is the lifetime which is at 200 hours
