Hi All,
I have noticed that sometimes at night on the freeways/roads that sometimes some S's HID change from white to blue/purple Lights while other S's Just have a constant White Light coming from there HID's. Is this due to the fact that i have been seeing S's around in which some have been lowered and therefore with the bouncy suspension causing the hids to somewhat change colors as they drive along? im a bit confused and was just curious to what causes this. thanks all for listening.

 

The color that comes out of HID headlights depends on a bunch of things... but to make a story short, I'll just explain the relevant point.

The angle at which you see the headlight directly affects what color you see. This can be applied to any projector based HID setup. Pay attention to ANY car that has projecters in the headlights and HID while its turning, accelerating or braking (causing dive or squat), or taking bumps. The color will change.

So basically what you said is correct, the change in suspension causes you to see the headlights at a different angle than you would on a stock stook. And therefore you see different colors emanating from the lights...

Hope that explains it...

 

when you say the HID projector headlights, are you talking about the ones that come stock on the S? i've also noticed though the very blue/purple style hids on BMW's and they are sometimes not as bouncy? maybe a higher burning rated light?

projector meaning the light is focused by a lens rather than mirror.

 

Okay, I hope you'll forgive me, but I've not been able to find exactly what "HID" stands for. I know they're xenon, referring to the gas and understand light temperature, but I haven't figured out the abbreviation.

 

High Intensity Discharge

 

Thanks!

 

no prob

 

It should probably be mentioned that this auto-leveling feature works during braking and acceleration dive and squat, but is not capable of counteracting the bounciness of road conditions.
