Stop with that "burn in period" bullshit. There is no such thing as "burn in per....
The OE bulbs which is supplied by OSRAM to MBUSA are NOT to spec of the PHILIPS bulbs that you receive with your car. What causes the yellowish output is the fact that OSRAM bulbs have a much lower temperature rating in Kelvin (3900K~4100K). If you look at the light spectrum chart you will see this to be the case. Most of the Xenon bulbs you see that burn a True White or even a blueish tint have alot higher temp ratings. Unfortunately, the OSRAM bulbs that you will get now from your dealer, are going to be yellow until MBUSA chooses a different supplier or more expensive bulb that puts out a higher temp rating. <br>
I installed a set of HIDS4LESS 6000K bulbs in my dad's S-Class and they looked fine, even bluer than the CLK's OEM. But I decided to swap them for a set of Phillips so I could take them for my M5 and the Phillips did the same thing. First turned BLUE and after a second or so, turned BROWNISH. SUP w/ that????
