I installed the 4300k HID conversion kit on my Mercedes S420 a couple months ago. I can tell you that this kit definitely delivers. The bright white is very close to normal daytime light so my eyes aren't so strained anymore for those long night time trips. I can now see so much more of the road, and that totally improves my visibility, thus allowing me to drive safer. Installation took me under 15 minutes, the hardest part was deciding where to mount the ballast!

For its price and quality I can back it up 100%. I would definitely install these on my 300E Benz and Lexus LS400. (Posted on 6/14/08)
