Nightbreaker Headlight upgrades?

[m00se]

I run them in all my cars and they are far superior to the standard H4 bulbs you get at shops. As Greasemonkey mentions, they don't last forever but now that I think of it, it's been 2 or three years since I last changed them on my VW T4 and it sees regular use. They lose brightness over time though so I might change them soon before they go out completely. I recommend them.
