No, they're not legal in any state. I have yet to be pulled over for them (been painted for over a year now). But when I had the snap on covers that go over your tail lights, I always had people shouting at me that my lights were out and got hassled by the cops alot. I do keep a spare set of tail lights boxed up in the garage in case I do get pulled over for them and have to go show proof that I fixed them. Only reason why I nightshaded this set of tail lights is because I got them for free from the guy I bought my new hood and front bumper from. He was going to toss them out since they were all delaminated and looked horrible. So I thought I could put them to use.
