making a hasty order for a new RH rear light and I wrong the part number , so I ordered PART N. LR028514, that is NAS type.
So I have the right NAS type light, while the left is ECE.
Does anyone know a way to disconnect or modify the side illuminated zone as for NAS veichles?
I seen on to NAS headlights, that is possible to disconnect these supplementary light, but I don't know if possible to do the same , for the rear lights.

same for the rear i think, just take the bulb out..

Andrew, this link might prove useful. Sounds like you might have to drill a whole in your new replacement light to disable the side light function

Surely if it's an MY12 light, it won't have any bulbs?  Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

Correct Alan, all LED, which means Andrew will most likely have to drill a whole in the new unit to disable the NAS side light/LED feature, as per the link above.

I'm very grateful to all
I figured, since the lighthouse is completely closed.
Any way, I will ask the exchange of the lighthouse, to my supplier .
if not accepted, I will refit my old light, and resell the NAS type
