Mercedes G Class A463 Multibeam Left Right Complete Headlights A4639061702/002 . A4639061802/002
part numbers A4639061702 (Left) and A4639061802 (Right) represent the Standard Chrome Multibeam LED Headlight units for the second-generation Mercedes-Benz G-Class (W463A) from 2018 to 2024.
The suffix /002 typically denotes a specific technical revision or “Q-level” (Quality Stand), ensuring they are the updated versions of the initial production run.
Technical Profile: Multibeam LED (Standard Chrome)
Unlike the “Night Package” units which have blacked-out internals, these feature a high-polish chrome finish inside the housing, giving the G-Wagon its classic luxury aesthetic.
-
Intelligent Matrix: Features 84 individually addressable LEDs that can “mask” out oncoming cars while keeping high beams active elsewhere.
-
Daytime Running Lights (DRL): The full 360° illuminated halo ring, which also functions as the turn signal (switching to amber).
-
Adaptive Features: Includes cornering lights and GPS-based light distribution (adjusting the beam for junctions or motorways).
Component Integration
To sell or install these as a “Complete” set, three distinct parts are required per side. If any are missing, the unit will not function:
| Component | Function | Note |
| Housing | The A4639061702/1802 shell | Includes the lenses and internal LED arrays. |
| Power Module | Main LED Ballast | Controls the high/low beam and DRL power. |
| Logic Module | Multibeam Matrix Controller | Manages the “intelligent” pixel switching. |

Professional Business Notes
-
Core Identification: If you are buying used, check the rear plastic “ears” (mounting tabs). These are the most common failure points. Even if the lens is perfect, a snapped tab significantly devalues the part.
-
Moisture Protection: The G-Class headlights are notorious for “breathing” issues. Ensure the rear rubber vent caps are present. Without them, moisture will contaminate the sensitive Multibeam electronics within weeks.
-
Shipping Strategy: These units are high-value and high-risk. I recommend shipping them in custom-fit foam-in-place packaging. Because the G-Wagon headlight sits perfectly vertical, any shift in the internal projector during transit can cause calibration errors (“Headlamp Assist Inoperative”) upon installation.
