The best Mercedes S-Class headlight upgrade depends on chassis, facelift version and original lighting package. W221 and W222 assemblies are not interchangeable. This guide compares the available LED-style options and total-cost considerations.
W221 three-bar LED upgrade
The W221 2006+ three-bar LED DRL projector assembly targets the earlier generation. Confirm wheelbase/body, facelift, xenon/ILS equipment, connectors and modules.
W222 Maybach-style LED upgrade
The W222 2014+ Maybach-style LED assembly targets the later generation. “Maybach style” describes appearance, not universal Maybach fitment; confirm exact body, production date and factory LED package.

| Choice | Best for | Main verification |
|---|---|---|

| W221 LED-style assembly | Older-generation modernization | W221 facelift and xenon/ILS system |
| W222 Maybach-style assembly | Later-generation visual upgrade | W222 body, facelift and module package |

Frequently asked questions
Can one S-Class headlight fit W221 and W222?
No. The generations use different housings, mounting points and electronics. Select the assembly by exact chassis.
Which year models are covered?
Available products target 2006+ W221 and separate 2014+ W222 applications. Confirm build date and facelift version.
Does an S-Class headlight upgrade require coding?
It may. Module transfer, coding, parameterization or component setup depends on the original equipment and selected assembly.
What modules should be included?
Confirm ballasts, LED drivers, control units and adapters using a written packing list for the exact version.
Is Maybach-style the same as Maybach fitment?
No. Maybach-style describes appearance. Exact W222/V222/Maybach body and mounting compatibility must still be confirmed.
