Once in my car, the bulbs of different manufacturers (regardless of whether brand or no-name) are always blown pretty quickly, I've tried this Osram here a few years ago. The illumination is actually a lot better than with andernen pears. Especially I can after several years use say the bulbs last much longer really. With me already more than 3 years after all others have failed by 1 year. Have again risen this here as a reserve to me now. Let's see if I will ever need.
