I thought that the main brake lights can't be on a moveable object like a trunk lid. With the new mules, it appears they have made all of the rear taillights part of the trunk lid. I'm basing this only on the fact that there is a line going down the outside of the taillights now that makes it look as if it's part of the trunk lid. With that said, I don't think that is allowed. ***I'M NOT SAYING NO TAIL LIGHTS ARE ALLOWED ON THE TRUNK LID. I just thought there is a law pertaining to the actual brake lights.
