These are great retrofits! They take your lights from boring, dim, yellow to exciting bright white! The halo light color now matches the nice bright Xenon lights. Very easy to install. On my '06 X5 4.8is I had to remove three bolts on the driver side for a power steering bracket, brace it out of the way a bit, remove the little halo light cover and replace the lamp. Nothing to do on the passenger side except remove cover and replace lamp. I did not need the supplied converter cables. I have before and after pics, but I wouldn't know how to share them. I recommend this product. I found these much less expensive than alternatives found elsewhere and I don't know how well those would work. Enjoy.
