w221 headlight retrofit - Best Method
- these have the h9 non infrared bulbs. So when you switch on the lights u will see them switch on above 20kph. That's how it's supposed to work but the original bulbs are infrared so u will have modify your h11 bulbs to fit in there.
- the fitment is okay. Not that great as it has to be pushed and pulled to fit.
-the Led amber indicator is too bright. You can see the sign boards illuminating but honestly I like it.
- the projectors are all over the place. No matter how much u adjust they will never be a straight cutoff.
All in all for the price I paid I am very happy. They are good value. They are a direct fit - plug and play. Just couldn't convince myself to spend over $1k.
please note that I am the only one judging my car. To everybody else around me they are perfect and nobody can tell the difference between these and the OEM.




I wanted to see from people that have made the retrofit, what works best, is most cost effective, and has anyone done it with Night Vision? I have OEM 2007 night vision and curve illumination, and cornering lights.
I already bought the 2012 headlights with night vision.
Here are the methods:
1) Wiring harness, 2010-13 Front SAM, Central Gateway Module + coding
2) MBSCA (Chris the Swede) wiring harness with magic black box
3) DCT/SonicMS wiring harness
UPDATE: There is a "plug and play" system now that works with Night View Assist! Under 1K on eBay. (seller "fishcake321")

If you pick up the eBay plug and play bixenon facelift headlights, (from link above - seller fishcake321) no wiring harness needed. "plug and play," no errors, this is the night vision version which only works if your car currently has night vision.
Good luck!

Yes, that is an alternative I looked at but Depo does not do pre-facelift and I wanted to keep the car stock looking. fishcake321 only supplies facelift headlights. Still trying to decide the direction I want to go. There are lots of alternatives.
Thanks for your reply




Do you only change buttons betwen displays?

I purchased facelift headlights, taillights and side view mirrors on eBay as well. The drls work fine for me. I also have the “drl” option checked in the instrument cluster.
