No; they don't self level. They are simply a Bi-Xenon kit retro fitted inside a Cibie lens. As I said, you just have to be careful where you set the height/beam. There is a fine line between them being too low to see and too high to avoid being flashed. If you excuse the pun, the difference between the standard Caterham headlights and mine as they are now is like night and day !!!
