Has anyone seen or used these Ambient Lighting kits offered by GM. They seem a little pricey for me, but I am still interested in them. It is GM part number 22922239 for the footwell and cup holder kit ($400) and 22983212 for the front footwell kit ($365).

"These Ambient Lighting packages provide a soft glow in the front floor footwell area and/or console cup holder of your Malibu to provide a stylish accent."
I understand I can do it for cheaper, trust me I have worlds of wiring experience, especially in LED lighting, but I am looking for just a little more info on what this product is.
For example:
-Are they the same color as the ambient lighting in the car now
-Are there already spots to mount these to and plugs available, or must it be wired in from "scratch"
-The cup holder is removable, so does it limit that, or does it also then light that big chest-like storage compartment under the cup holders
-The price seems really high for what is pictured, is there more to it, or is it just significantly overpriced (I was able to find the footwell and cup holder kit on several others sites for $342, still not a bargain for a $3 LED)
-Any more info or pictures would be cool.
Thank you.
