Mind you that do not expect those high performance halogen bulb will last like your old stock bulb. For example Osram Night Breaker Laser only have around 200-250 hours of working life.
Anyway, I assume you don't really drive with headlight on much of the time because your old stock halogen bulb last 5 years

I'm one of those lucky Preve owner that has lasting headlight bulb. Along my ownership of 5 years and 9 months I've only changed the light bulb twice, each time last me 2 years plus before they died (and I drive with headlights on quite frequently).
One funny thing is my top brake light has one led not working for years untill recently it suddenly revived itself.
