The DIADEM CHROME from Osram is a further development of the existing special bulbs that had only one chromatic filter coating and thus have still worked yellowish sunlight. The new bulbs of this type are also mirrored silver from the outside yet, so that incident light is "silver" reflected. Say: If the bulb does not burn, everything is silver-white. It lights up, the overall indicators is immersed in a pleasant yellow-orange light, which corresponds to the color of her a conventional, solid-colored turn signal.
For fans of yellow Sidemarker should also be noted: The color remains the same is also in the dimmed state, and does not drift into the red from.
A smooth, matte coating of the bulb affects the whole still a tad more noble, because there is no clear to highlight more of the filament.
I can not say anything yet about durability. According to the manufacturer it should be slightly reduced because the bulb should light than conventional slightly lighter in order to irradiate the filter can.
