The pattern shape is probably due to the ability of the factory to aim the low beam, muiti-bulb LED headlamps. Looking at the pattern, it makes sense that there would be a flat area in the center to provide a better transition of light coverage from left to right than would be possible with standard single bulb headlamps.

If not can you point me out on the location for the adjustment screw?
thanks

Interesting i have a related issue where i think the lights are not going far enough. I drive in the country side and its pitch dark so i was planning on asking the dealership next time i went in... i will try the adjustment on the LED lights. Is the screw for adjustment where it is shown in the thread snagit posted?
If not can you point me out on the location for the adjustment screw?
thanks

Old style halogens and even projectors could be aimed using a simple device - kinda like this:
But try and aim individual LED projectors with an aimer such as the one above... that's unpossible.

I think you are speaking to dealers using equipment to aim the headlamps to factory specification. Of course, anyone can twist a screw but the end result may not be to spec. I guess if you do it yourself and oncoming traffic flashes their high beams, you went too high.

The spread of the LED's and the manufacturing tolerances allow for the unit to be inserted during assembly by the robots who put the cars together. The height of the beam adjustment is also probably preset during the manufacturing. Individual LED's are not adjustable. If an end user complains of inadequacies then a dealer may adjust them by turning the screw but as the apparent lack of alignment would be noticed during the warranty period then having to pay $100 to get them aligned is only paid by people who don't know which end of a screwdriver to hold.
The bottom line is: if it's too low then turn it up and if it's too high then turn it down, if you want to align the levels of the left and right beams then park in front of a garage, hold the big end of the screwdriver and rotate it while it's attached to the adjusting screw. As for "within spec" then if you have ever driven a car before then you probably know where the low beams should be pointing.
These cars can get fairly complicated but aiming headlights is hardly the rocket science that is alluded to in this thread.

I did some research and discovered instructions on which end of the screwdriver to use (it's the pointy end). And I've never driven a car before so thanks for the tip!
