Because of the good reviews and the very well-successful marketing of Philips I have resorted to these bulbs. Full of expectations I have installed the bulbs after the very fast delivery immediately. Illumination and length are acceptable: there are certainly much better lights in this regard. However, I wanted to have beautiful white lights that match the rest of the lighting of the vehicle. In this respect: None, the bulbs are clearly yellow, as in the great depicted marketing Audi on the packaging. For me unacceptable to advertise something that is not realistic. Through my lens spotlight that is easy to recognize. I can not say anything about the longevity.
I'll probably revert to the Bosch +90: These have a super lighting, brighter & whiter light and have kept with me for 3 years. To recommend, but not legal in DE: Philips Diamond Vision
