Airbus has fitted the landing lights on its belly fairing
This is the first Eurowings' brand new A320Neo (MSN 10758) and it also seems to be the first time that Airbus has fitted the landing lights on its belly fairing rather than the traditional pop-out landing lights from under the wings
It's the new Multi-Functional Runway Light (MFRL) recently introduced. It offers drag reduction, weight savings, improved reliability performance, and there is no longer an aircraft dispatch condition associated with a fuel consumption penalty for a retractable landing light stuck in the extended position.
Actually, the MFRL is a re-design, re-allocation, and integration of the 2 Retractable Landing Lights and the complete set of the nose landing gear lights (2 runway turnoff lights, 1 taxi light, and 1 takeoff light), Thus, all the nose landing gear lights are removed and the Landing Light design is simplified (by removing the retractable mechanism).
