Ok so I didn't see a thread on this maybe I just missed it, I'm sorry if I did. So i bought my '12 TL about a muonth ago and the person who owned it before me used some type of red spray paint to tint the tail lights so I looked and did a lot of research and finally found a way to remove it...gasoline yup gas and a little elbow grease. It took some time still not finished but it's working..I'll post pics later
