I believe this thread is about the facelift LED lights while you posted about the original HID headlights on the nose cone pre facelift cars. Still informative nonetheless.
Hey, joelgjr: I did what you wrote, FABULOUS difference. But for me 3 turns was a bit much (people flashing me and not in that way) so I backed it down to 2. Perfect.
Thank You for helping figure out what is still a rather elusive topic to most (tried Googling it just now).
Just goes to show you'll often get much more accurate information about your car on these forums than by asking the Service Center. I'm not going to say they sometimes mislead customers to avoid helping with them with their issue (for whatever reason), but it's borderline....I had one headlight that was clearly way too high. SC used some lame excuse, cannot adjust headlight since you have air suspension.
Here's something to think about: With very cold winter nights, I get frosting inside both headlamp assemblies. I inquired to Tesla Service about this (still awaiting call from service manager to confirm all of the following) and it would appear that with LED technology the headlight assemblies are now ventilated and will absorb and release humidity with the natural cycling of heat/cold, rain or dry.
Issue with this is during cold nights the headlights get all frosted up... exactly when I need them to work well!! Case in point: yesterday night I had a close call with a deer strolling in the left lane of the freeway (fortunately I was in the right lane). Usually I would see them at the edge of the forest, at the tree-line, but yesterday I saw it with 1/2 a second of being at it's height, on the freeway. Good thing the deer wasn't in my lane or didn't jump in front of me!! But the frosted headlights failed me big time.
I hope this is not by design because if so, it has many inherent weaknesses:
- Cold frost at night hindering performance
- Accumulation of fogging and frosting cycles will leave smears and water stains inside the headlamp assembly progressively degrading appearance and performance of lighting.
- Possibly illegal design (basically law says we can't add film that would change the nature of the lighting, which fogging/frosting would do.
- Just the look of frosted headlight screams quality of fabrication issues: headlights being often the 1st part of a car we look at to recognize the car, Tesla cars usually attract a lot of looks and attention, and fogged up headlamps stick out like a sore thumb, you can see them from over 50ft away. This just isn't a good look for Tesla!
Here are pictures taken a few days ago with partial fogging:

Good point. The vents should be taped permanently. Just make sure not to close them up when the housing is full of humid air, then see them frost all up again! Relative humidity must be really low to avoid frosting at -20C (-5F).Perhaps you should tape over the vents during the winter weather...

Essentially any car on the market today has excellent LED headlights. Oddly enough BMWs suffered for a few years from early HID projectors that aimed too far down and thus not far enough down the road.I think I'll have to have a play around with this adjustment too, I can't stand the low beams in my 2017, the highs are fine though. If only Tesla had driven an X5 (my wife has one) before designing the Model S headlights to see how it is done properly.
