I've been running +90 nightbreakers for 12 months/22000km now and drive with my lights on 90% of the time and no issues..... yet :wink:
I might get myself a second set for changeout when they do give up the ghost though.
To quote myself and revive a thread :wink: I blew one of my Osram +90's today after 14 months (approx 27,000km) use with headlights being on almost permanently whilst driving - Blue Graphite is a very low vis colour!
Very happy with their performance to date so have ordered a new set from powerbulbs today.
