Now have installed since March 2010. This lamp. So far, about 2500 km on the clock. Since last about 1 month unfortunately constantly water in the light when you're driving through the rain for a few hours, does not everyone is ok but unfortunately can not be avoided with me. The light otherwise is just fantastic, unfortunately, by the inflow of water to the reflector cloudy and I now have an extreme light loss. Let's see how B & M react and if you get a tip to open the lamp and clean the reflector. Therefore, I also only 3 stars. For the light I would give 6 if possible.
So the Comment by the supplier was "can sometimes occur", which has been not wirlkich helpful. So Busch and Müller angemailt, a day later, the return mail I get is to send in the light. Less than a week later, a package with a new Leuche in the mail. So service of B & M, I can only recommend does make sense to buy quality products. Hope the new lamp is tight this time.
