I am after a test in Auto Motor und Sport hear about these lamps. I have always annoyed me about my little dark and yellowish light in my Twingo. I then bought myself these lamps. And what can I say: Although you bring nich 130% more light, but they remain lit, white and Lichtkegle is also wider, so that the Reche kerbside is significantly better illuminated. An absolute gain in safety! I can recommend the lamps fully! I did not think that there is such a big difference at H4 lamps.
