Who makes H7 bulbs for Bosch?


Newly Enlightened

In a recent test by the English Which magazine the Bosch Pure Light H7 had the best light (better throw and brightness) in the low beam position. It seems to be better than the Osram night breaker and philips extreme according to the test. Bosch Pure light is their entry level bulb (Bosch has a plus 50 and 90 bulbs as well). I wonder who makes these bulbs for Osram? It says made in Germany on the packet. Any comments on the test result or the manufacturer?
