Mercedes G-Class W463 AMG Full LED Multibeam Left Headlight A4639068902/001 .A4639067602/001
part numbers A4639068902 and A4639067602 refer to the most recent iterations of the Multibeam LED Headlight (Left/Driver Side) for the Mercedes-Benz G-Class (W463A).
The /001 suffix indicates a specific technical revision level. These are often the “Darkened” or Black Series units found on the G63 AMG and models equipped with the Night Package.
Technical Specifics
These are high-specification units that combine the matrix LED technology with the aggressive “smoked” aesthetic.
-
Multibeam LED (Code L57): Features the 84-pixel matrix for active light shadowing.
-
AESTHETIC: These part numbers typically correspond to the Night Package (Code P55/P56) versions, featuring darkened internal housings and a more aggressive look compared to the standard chrome units.
-
Precision Optics: The circular DRL ring acts as a high-intensity daytime light and a sweeping amber turn signal.
Comparison of the Two Part Numbers
In the Mercedes-Benz parts ecosystem, having two different numbers for the “Left” side often indicates a superseded sequence or a change in manufacturer (e.g., Hella vs. Automotive Lighting).
| Part Number | Type | Status/Context |
| A4639067602 | Left Multibeam LED | Often the original factory-fit part number for 2021–2023 models. |
| A4639068902 | Left Multibeam LED | Typically the updated/replacement part number (Supersession). |
Note: Mercedes frequently updates part numbers to reflect minor internal changes to the LED controllers or the sealing gaskets to prevent the common “fogging” issues in G-Wagons.
Fitment & Compatibility
-
Chassis: W463A (2018–2024).
-
Models: G63 AMG, G550, G400d.
-
Installation: These require the LED Power Module and the Matrix Logic Module to be attached to the rear. If you are swapping from a standard chrome unit to this darkened version, it is a direct physical fit, but you must ensure both sides match to avoid an asymmetrical front end.
Business & Inventory Strategy
-
Check the Glass: Because these are “Black” internals, any scratches or pitting on the outer polycarbonate lens are significantly more visible than on chrome units.
-
Mounting Tabs: As with all G-Wagon lights, verify the three main mounting points. These are “Serviceable” (repair kits exist), but original, unbroken tabs are a major selling point for high-end clients.
-
Shipping: These are high-value items (often retailing for $2,500+ per side). I recommend shipping in double-walled boxes with heavy-duty bubble wrap or spray-foam inserts.
