So I thought that I would ask this because It has been bothering me. At night when I am driving it seems that the HID's are always leveling. I can tell at times that it adjusts to the difference between the car and the road. Could it be that the self leveling device is always adjusting? One would think if that were the case, it would wear out that system? Moving up and down for every little bump and move. Does anyone know if it continues to adjust? Or is something wrong!?!?

 

it always adjusts. it needs to adjust so that when you're rolling uphill, it points down and shows you the road as opposed to shooting into the sky, when going downhill- the opposite.

as far as little bumps here and there - they always adjust. my dad's gs4 has the same setup and when i drive it - they make me think my eyes are jumping since they adjust so much.

 

yup it's always self adjusting, otherwise, what's the point

though i drive my sc430 and over bumps and such i don't think think it adjusts that bad?

 

and in europe i think HID headlamps are required to have auto self leveling by law

 

I like the fact it auto adjusts. Its fun to pull up behind someone and punch it to get the nose to lift and the lights to dip. Interesting feat to say the least.
THe purpose is to keep that cutoff line from blinding oncoming drivers and keeping the light focused on the road. Impressive technology!
