Greetings all,

We are proud to announce that we are the first shop to successfully retrofit the facelift headlights onto a pre-facelift W221 without the use of messy resistor packs or hack-job wiring. The retrofit process we utilized was completely plug and play.



Here you can see the original pre-facelift headlamp.



New facelift headlamp unit.







Here you can see the LED DRL system being fully functional.



As well as the LED turn signals. All OEM functionality is retained. If one were to upgrade the front bumper with the facelift (2011+) with the LED DRL fog light strips, all the connections are ready for plug and play operation as well.


We used a custom plug and play retrofit harness in addition to retrofitting a 2011+ model year SAM (Signal Acquisition Module) and custom programming for everything to function properly.





Below is a video demonstrating the facelift headlamps in action.

awesome! nice video to show the headlight functioning!

 

Here are some more pictures documenting another the W221 Facelift S63 AMG full conversion.



The car is a 2008 S550. We retrofitted OEM facelift S63 AMG front bumper with LED daytime running lights (DRLs) in addition to the OEM facelift W221 headlights with LED DRLs, precoded front SAM (signal acquisition module) and our proprietary plug and play wiring harness. In addition, we retrofitted OEM facelift rear tail lights and OEM facelift S63 AMG rear bumper as well as a custom quad exhaust system.

Here you can see that the car already has the S63 AMG facelift front bumper installed with LED DRLs but still with the prefacelift headlights.




We removed the front bumper...



Here's a few pictures of the plug and play connectors.





New facelift units installed.
