The source listing showed a price of €139.00 when the data was collected. Prices and availability can change, so treat this as a reference rather than a permanent offer.
Compatibility and fitment checks
Confirm the VIN, door-light housing, electrical connector and control-unit support. Physical similarity does not prove that the vehicle electronics will recognise the projector without coding.
Before purchase, compare the complete number with the existing item and request confirmation against the vehicle identification number where vehicle-specific fitment is involved. Also check dimensions, connectors, mounting points, colour and any required option codes.
Installation and use considerations
Protect the door trim, disconnect the original lamp carefully and avoid pulling on its wiring. After fitting, code the vehicle if required and test both front doors for correct operation and warning-free function.
If the work affects electrical systems, vehicle coding, cooling, wheels or any safety-related component, professional installation is the sensible option. Inspect the delivered item before fitting and keep its packaging until compatibility and function have been confirmed.
Who should consider this product?
This product is most relevant to owners and workshops that have already identified A2478207403 as the correct number or are comparing it during a VIN-based parts search. It is less suitable as a speculative purchase based only on a photograph or broad model description.
Our verdict
The genuine Mercedes-Benz 3D Star LED Door Projector is a distinctive genuine lighting upgrade for supported vehicles, with electronic compatibility and coding being as important as physical fit.
