I bought the bulbs since left something in my more than 10-year-old car to be desired light output. There were also simple brand lamps mounted as these I ausleuchteten the road very dark and streaky looked for brighter lights. Since most brighter lamp in the tests have a shelf life begrenste, I decided for this model plus 50%. After installation I realized actually recorded a much better illumination of the road. Everything is brighter and more illuminated if there is a blue or yellow page can be found on the lamp realize it, but on the roadway rather not. This may be due to my eyes, or be too low, but I can only recommend this lamp. For durability, I can not say anything, because it is only one month in use. Important when buying at H7 thing to remember for what you need the spotlight lamp, spot or reflector. If the durability of the figure quoted relates to buy only this model.
