As in the two customers pictures of me, 4 lamps in 2 different cars are now burns in the truest sense of the word after 7-8 months. 2 lamps are gone off literally and 2 were for the inner deposits in the glass bulb on the verge. Fortunately (Vectra C / Mazda 3 BK) DE headlights are in two cars built and no free-form reflector it was thus ruined. So not OSRAM! Before questions come, no, I did not touch the glass bulb with your fingers.
