well I wanted to get cool bule I was wondering how long do they last please. Be it more than 2 years.

 

No they probably wont last that long.

 

Since you're in Poland, here's something I've got to add.

In the US Sylvania SilverStar is a blue coated appearance modification light, but in Europe, SilverStar from Osram GmbH is a high performing clear bulb with more output (and shorter life).

Suggestions of specific product lines from the US may not correspond the same in Poland.

 

i've run the osram's in my GTI for the past year and a half. i only get 6ish months out of a set. they are great for output but longevity sucks
