Hi
Three months ago I upgraded my bulbs to Osram Nightbreaker H1/H7.
Here in Denmark it is required that you have the low beam(?) on as driving lights.
So 3 months and about 10.000 km later (don't know how many hours that is) the first Osram H7 blew?!
I contacted the dealer where I bought the bulbs and they basically just said bad luck, buy some new ones.
I then contacted Osram in Denmark and they said that the Nightbreaker is giving about 80% more light than a standard bulb and therefore the expected lifetime of a Nightbreaker bulb is about 220 hours
And if the headlights are "overpowered" by as "little" as 1 volt the lifetime might only be 50% (thats about 110 hours )
I know my old Citroen Picasso blew the bulbs every 4-6 months because of "overpowering" but are the 500 as bad as that?
The Osram guy did send me 2 new H7 as well as 2 new H1 bulbs free of charge so that was very nice
Meanwhile I've ordered and installed Philips Nightguide H7 and we'll have to see if they will last longer.
