Mercedes G-Class W463 Headlights / A4639064702 / A4639064802

part numbers (A4639064702 for the left/driver side and A4639064802 for the right/passenger side) refer to the Multibeam LED Headlight units for the modern Mercedes-Benz G-Class (W463A / W464), produced from 2018 through 2024.

Technical Specifications

These are high-end, electronically controlled lighting units. Unlike the older bi-xenon or standard LED units, these feature the “Black Series” or “Darkened” look often associated with the Night Package (Code P55).

• Technology: Multibeam LED with 84 individually controllable LEDs per lamp.

• Visual Style: Tinted/darkened internal housings (common on G63 AMG and Night Package G550 models).

• Functions: Includes Adaptive Highbeam Assist Plus, cornering lights, and the signature circular LED Daytime Running Light (DRL).

• Control Units: These are “bare” housings. They require the LED power modules (ballasts) to be transferred or purchased separately (typically part number A213900… or similar).

Fitment & Compatibility

While the G-Class has used the “W463” designation for decades, these specific parts are for the second-generation redesign.

Inventory & Value Notes

For a business specializing in luxury spares, these are high-value, high-demand items due to the G-Wagon’s popularity in the customization market.

• Condition Check: When inspecting these units, the most common “hidden” damage is at the rear mounting tabs. Because the G-Class has a vertical front end, any minor impact can snap the plastic tabs even if the glass (polycarbonate) remains uncracked.

• Glass/Lens: These use a high-impact polycarbonate. Ensure there is no “crazing” (internal micro-cracks) caused by harsh UV exposure or aggressive cleaning chemicals.

• Shipping: These units are surprisingly heavy and sensitive to vibration. They should be shipped in “suspension packaging” (floating in foam or plastic film) to prevent the internal projector motors from calibrating incorrectly after transit.
