I use LEDs in limited applications, and I usually do not try to color highlight. I think it's cool when people do it, but I don't think it's for me for every day.
I did the warm white LED pinbit kit for the clock ($6). It's awesome and very much retains the original look and feel IMHO.
I also did warm white flex's (from cointaker) on the inner door panel inserts that have one off-center bulb to light them.
Now to find some 545 LEDs for when those go in the backbox... anyone? anyone?
