I just received my four projector puddle light set today from Norm, and installed it in about 30 minutes. See link for pictures. It Comes with great instructions with just about all the installation tools included. You will only need a drill and maybe a flat head screw driver to pry out the existing lights. Currently, I highly recommend it. I will keep you posted on the longevity...
I couldn't upload the images directly, so I here is a dropbox link.
