The H7 bulbs come in the original Philips-plastic packaging. Enclosed are fortunately Standlichtlampen. These are - just like the H7 - bluish shimmering. So the yellowness should be mitigated somewhat in the parking light, which works pretty well, but it has no practical use.
The lamps themselves keep their promises to provide better illumination. The light is much brighter than conventional bulbs, without acting silly blue.
The increased luminosity to what is described on the package, at the expense of longevity. The lamps are now several months in daily use and so far there has been fortunately still no event of default.
Conclusion
=====
Even if the bulbs are slightly more expensive, I'm willing to pay this charge that I at least do everything in low ratios for the best possible way to see.
