All,

I want to check the aim of the halogen headlamps on our 2019 4matic SUV before I install some brighter bulbs, but I need some help.

Most headlamps have two adjusters to control vertical & horizontal aim. I see one adjuster on each side (a white screw(?) with a crosshead opening) but not a second. Does anyone know where it might be located? I tried to upload a photo, but kept getting an error after only uploading 50% of the file.

Also, is there any MBZ documentation or factory guidelines for headlamp aim available? If not, I can fall back on the instructions linked here. Thank you.

Hi,

there is only one adjustment available on halogen headlights. Just up and down, no side adjustment.

also I recommend lasfit led bulbs. They are very bright and white.

Edit 1: added photo of passenger-side headlamp adjuster for reference

Hi Altay,

Thank you for confirming that only one axis of adjustment is available. I can't find what's not there.

For those interested, here's what I saw under the hood: one adjuster, in the red square:




Thanks for the recommendation. I'm wary of how well LED bulbs work in headlamps designed for filament bulbs, but will check them out. I'm leaning towards the H7 bulbs listed here.

Regards,
Cyrus

Lasfit has special design for mercedes benz cars. I know usually they dont have good pattern for halogen design but these are perfect fit and has very good pattern. Just fyi 👍
