I wanted to keep you posted on the developments in this area. artsci had developed the lighted T for the front emblem. Some of you have seen it on my MS. Now, they are working on the rear T emblem It is supposed to turn on when you press your brakes. If you are interested, here is the post.
Been watching it closely...will acquire once it's available. If I recall right, it's on anytime the headlights are on (in a dim mode, just light tail lights) and when the brake is pressed, it brightens--mimicking the brake lights which do the same.
