Well actually, I learned you could choose green, red, or blue with these sill plates which I'm told are for the 2010, 2011 model years. They were meant to be an extension of the ambient lighting feature but I have yet to run into a '10 / '11 owner who can verify this. I bought them new for $85 thinking they were the standard red lighted versions that come from Ford Racing but when I received them, the wiring looked nothing like the Ford offering. Instead there was a four-hole connector coming off the back of the plate. Experimenting with a 9-volt battery, I learned that one hole was the ground while the other three holes were power leads each representing the primary colors of green, red, and blue. Once I found blue, I tapped the wires and installed the sills. Very pleased with the end result.
