This is what bothers me, I wouldn't trust it unless it was from a brand like Hella. From my experience this stuff on Aliexpress doesn't last very long and 900 odd quid is a lot of money for something that might not last a long time. They do look nice though!
checked, they are from Taiwan and cost around 500 euro for a pair plus shipping here in Hong Kong. wanted to get a pair but same concerns as you guy, 500euro is not cheap and dont want to be a lab mouse
Not quite the same thing, but a similar effect (albeit with lots of work). The whole thread is a very interesting read; the OP is a proper trooper with his effort!
It is a better approach since you retain the original headlights but it is a heck of lot work and I wouldn't be comfortable taking these headlights apart and again the durability of the LED kit is questionable. I fitted a similar LED angel eyes kit to my old E46 (the headlights on that was a doddle to take apart in comparison to the Zed), they looked great but after 3 years or so some of the LEDs began to fail. So I would not be surprised if this kit lasted the same amount of time.
I have seen a company that does these conversions as pictured in the aliexpress ads, I think they were in California.
You might well find that the Chinese item is a modified OEM light!
After all they are probably made in China anyway
I have seen the company in the USA before too, I think they modify the original headlamps, probably they use the kits from China but I wonder how many years warranty they provide. If you look at the video in the aliexpress link you can see they are replacement lamps and not modified originals.
Update: Had a chat with one company selling these. I took a photo of my current headlight connector and sent it to them. They compared and said it's the same connector, but with some extra wire/pin. In other words connector should fit.
AFS of course needs to be coded off. I did some googling and found E90 equivalent: "Remove $524 from VO from the PDF below showing you how to VO code...Then use expertmode and code default to CAS and NFRM and your done"
