I bought MK7.5-style headlights from AKD ("GTI all LED" option) on Aliexpress. They're for MK7s with factory halogens. I'm stumped after testing the AKD headlights using a multimeter and DC power supply.

None of the pins appear to turn on the low beam (D2H LED bulb) nor can I tell what Pins 1, 2, 3 do.

Also confusing is that Pins 5 and 6 have 0.2 ohms of resistance between them. This was the case for both driver and passenger headlights. I confirmed the D2H and H7 bulbs that came installed function as expected when tested outside the headlights.

Any ideas on what I could be missing, or what market the AKD are wired for?

For another perspective, here's the backside of the female connector in my car:

Pin 1, 2, 3 are for the manual headlight range adjuster. It’s mandatory in Europe e.g. and I guess in many other ROW countries.

Pin 6 should be the lowbeam Pin. Have you tried Pin4 & 6 to 12V and Pin5 to ground? Not sure what electronic they have inside of the light but I guess the DRL dim w/ lowbeams on, maybe lowbeam works w/ DRL on only?
