Had same sort of prob with mine, when i had the car lowered both headlights were pointing at the floor, after a while i found the cause! it was the electric motor that self levels the lights, it had run all the way off the end of the adjuster causing the lights to drop to there lowest point. I took the motor's off both lights opened them up and hand wound them back on, i then re-fitted them back onto the headlights, they were perfect for about 2 seconds then the self leveler motor spun them off again!! So after doing the above 3 times i then decided to dissconnect the power to the motor and just leveled the lights manual (using the white nut while parked facing a wall) Now they are ok they just dont have the self leveler as i have left it dissconnected.
(if anyone know's a better way round this let me know, im sure im not the 1st to have come accross this)
