Headlight Adjustment. Help please!
My friend that just became a CF member but not able to post thread just yet asked me a question that I had no idea what the answer might be so I thought I'd ask you guys since you have always been very helpful and very knowledgable.
So here's the question, his 2006 C6 MN VY has one light that is a bit pointing down and he needs to have this adjusted. He says he has called many dealerships and everyone just scratches their head and can't help him. Do you guys know how he would be able to do that? Would he just have to unscrew the entire casing and put it back on? Thanks guys.

If it's the drivers side that's lower than the passengers side it's meant to be that way.

Sorry can't help but...
I believe I have a similar situation. When parked my lights are in a good position but once I start driving my driver's side HID begans to "shake". I can't really explain it other than it gets brighter when it bounces so I think the mount is loose or something. This was told to me by my dad and if he wouldn't of told me I'd never of know because the HID fills in the road so well.

Why would the dealership just scratch their head. The service manuals have pages of information on how to properly adjust and aim your headlights. I scanned the information months ago for someone else but naturally, I purged the files.
Headlight aiming is only adjusted vertically. Vertical aiming of each of the composite headlamps is done by turning the adjusting screws which move the headlamp capsule in relation to the headlamp frame. The vertical adjustment screw is located on the inner wheelhouse (raise the hood...the adjusting screw is located roughly on a line with the 'top' edge of the headlamp glass along the engine bay wall near the headlamp).
Various Governmental requirements dictate headlamp aiming....the headlamp aiming procedures are somewhat involved using a screen with a grid on it....many diagrams.
I'm leaving in a moment but if I can later, I'll scan the pages on my daughter's flatbed scanner and I could email the information to you (as image files). If you want, PM me your email address.

No need Wayne but thanks to everyone for their input. I referred him to Orange County Corvettes and he called me back to give me the good news that Sean was nice enough to give him the info needed and it is exactly what WayneO said. Just a matter of turning one single and simple screw.

Here is revival of an old post. I would have absolutely no idea how to adjust my lights without it! I started banging them, trying to move the housings with my hand to no avail. I just had carbon fiber headlights installed and the beams were not aligned and the search button was my friend with this "Holy batman" old post..........an oldie but goodie!!!!!!

A Forum Search for "headlight adjustment" would probably turn up these pics.
I've re-posted them a couple times, sorry I can't credit the originator.

For some reason my headlight adjustment has raised causing it to point high and blind on coming traffic. I tried adjusting it with the Allen wrench and at first it fixed it. Then I banged on the headlight some to make sure it was good. As I started banging it the light starting moving up back to the high and out of alignment position. So again I adjusted it. Same thing. Now it won't even adjust at all. It just spins and the headlight won't move up or down. It was recently in the body shop and I had to take it back to them yesterday due to the headlight not being properly aligned. Do you think my headlight is damaged? I did have a hit and run in a parking garage, but there was no damage to the headlight housing. Only the bumper underneath the housing. Can this be fixed?

Sometimes info just doesn't matter when IMHO, so thanks again, I would have never guessed that's what that was

I find it amusing that someone above said they tried banging the lights and trying to move the housing around as an adjustment method. Really? I understand there are some among us that have the mechanical sense of a mushroom, but come on? Are some that ignorant?
