No error codes for the brake lights. Below is a picture of the stock vs LED lit up (not my pic, its from the Jlevisw.com site where I purchased them).
As far as the overlays go, I know they don't look perfect but I wasn't trying to spend $800 + on new (LCI) lenses to eliminate the amber, and I am afraid to crack the current ones and remove the reflector so I figured for $20 I couldn't lose. I guess until I hit the lottery or get a new car this is it!
