I have to say I habs me thinking long, but by positive comments in various Internet forums I decided me to the x-treme Vision to buy. And I have not regretted it. Hab 3 packs each bought one for low beam, high beam and fog lights. I have a Grande Punto with Dayline headlights. For low beam, the x-treme are definitely brighter than that of the Dayline, the high beam light it even much further than in the Dayline. And at the Neblern are the x-treme course better. I am very satisfied with the brightness of the X-treme Vision, also is the light of the x-treme pears significantly whiter than the headlights or light from the original Punto.
Update:
I've been to replace any bulb. And they've now sold for 2 years
