I have been thinking about replacing GS headlights with the HID's from a salvaged GT. I know the GT has self leveling motors fore and aft, so I would likely have to ditch those and just wire in the housing and replace some fuses etc. I am curious though, as to an approximate time frame for the lights to become unaligned. I am not up on the luxo car market, so I don't know if self leveling motors is standard practice now days or if Mazda, or HID's in general, have problems with the lights becoming out of alignment rapidly?

 

The self-leveling mechanism uses sensors at all 4 wheels which are also part of the DSC system. Honestly, I can't notice the leveling system. I'd just mount the lights and leave the leveling system off.

 

Ohhhh, is it a dynamic leveling system? I assumed it was just used to keep the lights aligned so you didn't have to go to a dealer once in a blue moon. Then I couldn't figure out why that would be necessary. But, if it's to adjust the aim during manouvers, that's kinda cool, but I really don't need that.

Thanks

 

According to the service video, there are sensors on the drivers side rear and front lower control arms. So only two on the drivers side. I've seen the lights move, only when I first start the car. My lexus, on the other hand, is crazy with constant adjustment. Every time you hit the brakes or gas the lights auto adjust.
