When I got Night Breaker Plus these Osram, I just installed a lamp in there left to see the other originals to the direct comparison. Here was right to see that the Night Breaker Plus actually been very bright in comparison to the original lamp. At this point I saw has always, whether a distinction could be seen, usually I built the lamp straight back, but not in this case. 2. installed lamp and waited until it got dark.
The light yield in the dark was very good, suddenly we saw more than before. Here you can see a clear difference.
It is said everywhere that life is not outstanding, because the lights are so bright.
To this end, I can not say much, except that I now drive this since the end of July and so far no loss of quality is still recorded. My car also has a Coming Home function, whereby the lamps are often switched on or off and straight back, and that made so far but nothing.
Once a lamp refuses to work, I try to think on it, to edit this post.
What to look for, some vehicles have something milky glass headlights, this might not be such a difference to notice how in clear-glass headlights.
