Headlight level sensors and ultra low ride height

Just got my 60k service and some other maintenance taken care of and my tech showed me that the headlight level sensor on my ls430 is under stress...which it is from my ride height. 

Under inspection, the rod on the rear control arm has bent a bit. There is a range of adjustment on it, which leads to my next question. If I adjust it and set it at the lowest point, will it readjust according to the new height or will it require calibration?

Lastly....has anyone actually had an actuator break? I don't mind if it breaks, I just rather not look at the light on the cluster. :pat:

yeah, i am actually kind of surprised that they didnt adjust it for you

not sure if this pertains to this issue. my lights would auto level and be to low so I unhooked and tied the arm so it would stay in one position and adjusted the lights to my likeing. solved my prob
