It's your Xenon headlights leveling sensor. Having any problem with headlights out of alignment?

As noted above its for the auto-leveling headlights. Can cause your lights to be incorrectly aimed if you may or may not have noticed.

Nope, E39 doesn't have 'Adaptive' (or swivel) headlights.

So... what's the purpose of these?
HowStuffWorks "Self-leveling Systems and Future Headlight Technology"

Self-leveling headlights have an additional level sensor that determines if the car is tilted forward or back. For example, if a car is driving over a large bump, when the front of the car hits the bump, it lifts up. Standard headlights would briefly point up into the sky until the rear of the car moved over the bump and the car returned to a level position. You may have noticed this if a car driving behind you at night passed over a bump, such as a railroad crossing. The other car's headlights would flash briefly, as if the driver had blinked his or her high beams at you. This is actually the car's headlights temporarily pointing up and into your eyes instead of down at the road. With a self-leveling system, electric servomotors react to the level sensor and keep the headlights aimed down at the road, no matter the position of the car.

Im sorry but that is so damn dumb.

Is it really worth the extra parts and having to replace this part because it is brittle, just to not have headlights VERY QUICKLY flash at someone.



Please.



So Dumb.

Failure of the self-levelling mechanism for HID's could well be an MOT failure in the UK, if I'm not mistaken. MOT testers, please correct if this is no longer the case...

No, I understand. Im sure the Department of Transportation for all states here would be the same way with the rules as well. I can see the purpose of these now.

Well get some idiot with people in back, load of crap in boot, blinding everyone.
This stops it.
As said think it's a must have for hid's.
Also is nice to watch them adjust as you drive along.

Any way you can test the leveling out by say, removing the link and moving the arm/lever up and down? I have DDM DJ Auto headlamps installed, and I'm not positive the auto leveling works (only because I was unable to test them).

If it makes you feel better, your post just helped me figure out where the leveling arms are located - thanks! :thumbsup:
