I have the lamps replaced in our Roomster in June 2012. (H4) Compared to the first original lamps (veeery normal Bosch lamps) are truly amazing brightness differences. When we bought the car, we were annoyed us very excited about the light output of Neufahrzeuges.Nachts ride was really bad. (Our old Mondeo with H1 lamps light was) in a test over H4 and H7 bulbs we came up with the Bosch +90. The lamps are so changed in the Roomster in 5 minutes, and lo and behold, at last a super bright Licht.Wir never thought that a lamp replacement kann.Die so make a difference light bulb can I advise all that the about their Serienfunzeln ärgern.Über durability, we can not say much until today they shine unverdrossen.Der small extra cost compared to the original lamp from the workshop is certainly easy to get over in the light output! Since the lamps still light up at 18 months, from me 5 stars!
