Because of my low beams broke down recently, I was forced to sit down with the issue low beam apart. What do I need fÃ'r a pear, how can with my car (Golf V) be changed? After some research and some back and forth (due to but partly false recessions) I decided fÃ'r the OSRAM NIGHT BREAKER UNLIMITED. It turns out to be right. Am absolutely Ã'berzeugt of the result. Had meanwhile fear that the blue shimmer (which I did not want to, because that looks very hÃ'sslich and cheap in my opinion). But this is not so. The before / after effect is super! In daylight you see almost no difference (ie change in the light and go down again in the evening and watch :) If you stand next to a car with xenon, one sees natÃ'rlich the difference. By contrast, this act still yellow. But there are indeed "only" halogen bulbs) Had natÃ'rlich the problem that my parking lights (which logically always lights up together with the low beam) continues to be yellow. Very unschön. Have it researched back down and decided fÃ'r the OSRAM COOL BLUE INTENSE. Here again was the fear for the purpose of blue. But this is not so. The two bulbs will fit very well together! About the life I can say nothing, have these replaced until the weekend. Will the term ergÃ'nzen with me if necessary!
