I wanted to switch from yellow lights to white lights. I realize that I have succeeded. I received the lamps and used directly. Everything fits just fine. This is a Ford Fiesta 5 BJ 2004. Ironically, that night I had to drive in fog. So directly Stiftung Warentest. I am fully satisfied after several hours. I can not say anything yet about the life of the lamps. But I like them. There is no longer such a dull yellow. In addition, even a little bit bluish color with the lights in it when I look at from the outside me. So definitely recommended from me. I notice also that these bulbs better illuminate the road edges. The high beam seems to work very well. The price I was now ok and not so expensive. One star deduction due to high shipping costs. Packaging is not so great. Could you actually send a large Internet shipping company for free. Well finally I'm happy with the Bosch 90+ H4 lamps. Recommended !!!
