The light color is to look very white in the daytime running mode without blue. That was also the aim of incorporating. The pilot Blu-Xe have with the dipped beam a very low yellowness making them no longer as beautiful pure white. Beware of luminous paint her perfectly lamps as the Philips Blue Vision. In conjunction with the M-TEC Superwhite lamps they are a bit yellowish, unless the low beam is switched on.
Conclusion: Very good lamps with a, I think, very long lifespan (2 years in the first sentence) and a beautiful white light in pure daytime running operation. A star deduction is available for the fact that the pilot Blu-Xe light yellowish with the dipped beam and no longer so white. For the price you can not go wrong in any case.
