Did the end of 2009 the standard Abblendlampen H7 Osram Night Breaker against substituted. I had read that this would (like all other tuned lamps also) a short life. The light output was directly significantly better in this winter time - So that was an absolute For-profit. Have constantly carried a spare lamp box and glued to the first failure (so 4 - 6 months) waited - BUT: It was not a failure. After beaten --drei-- years a pear is now in default; and at approx. 70 tkm route. Also goes with me when raus and purely go to the garage constantly on the low beam by the light sensor. So 4 a day, 6 or even 8 power-impulses, which indeed the life not just to be beneficial. A friend of mine has also installed at the same time these lamps - but moves significantly less km - who also held until recently. All in all a super lamp. Now I have my spare stock in it and I now bought a new replacement the "Plus", which is to hold Yes again for longer. Am thrilled by the luminous efficiency and lifetime.
