Hi all, I have the same problem on my corolla ascent. I found the thimble switch on the steering column to be sticky/ dirty. They are little fingers/ platinum points that needed to be cleaned with some fine sandpaper. Also bending the fingers will also help to give better contact for the lights. There are 3 fingers and the middle one is for the park & tail lights. Hope this helps resolve your problem. Sakthy.
