I found on my headlights this circle style bolt and it has little teeth round the edge of it. I remember on my old car it had this type of screw and when I turned it, it did adjust it up and down but when I tried the same style screw on the back of my camry headlights it does nothing? :( I'm spun out on how to adjust em, my left headlight seems ok, just the drivers side projector seems abit more blinding
