Also, I had already seen many H7 bulbs tested (Mtec Super White, Philips Blue Vision, Osram Cool Blue, etc.) to simply not to drive with tealight yellow pears through the darkness. None of these bulbs comes remotely turn on the Philips Diamond Vision. Here are some product features ... my current vehicle ... VW Golf 5 with standard clear glass headlights. Dipped Philips Diamond Vision / high beam Mtec Superwhite / parking lights LED bulbs. - Light color: 95% know / 5% blue / no yellow tinge. Compared to real Xenon light almost no difference is seen. - Light intensity naturally weaker than genuine Xenon light. - Light output as standard halogen lamps, wet unfortunately somewhat smaller, but disruptive in any way.
Conclusion: Those looking for absolute white light with a hint of blue and yellow, without which I can recommend the Philips Diamond Vision highly enough. Only downside, not admitted STVO, without E-mark !!! To evaluate the life, I can not say much because I only recently have the bulbs in use.
