Technical Interior light is dead.

[Rode Willem]

The interior light near the sliding door at foot level in my Knaus Buscamper 2018, which is based on a Fiat Ducato 2017 2.3D 130 Multijet 69Kw, version 250a7mfb hyt1, is not functioning. For more details, please refer to the attached file. Any suggestions would be appreciated.
