Hi Steven, remove fuses F4 10A, F21 15A and F31 30A, all in the auxiliary junction which is located between the rear seats.
Make sure the radio is switched off on the panel first.
Have a look on this page for the correct VIN range, then with the part number just google it for suppliers; https://parts.jaguarlandroverclassic.com/parts/index/part/id/400.1293.3744.16495/brand/jaguar/
If you can’t source them from electronic stores then these guys will be able to do it for you. https://www.ebay.co.uk/itm/256406369024
I have read of people repairing the lights themselves so it is more than possible.
This guy may have all the parts you need, worth a call;

Use a piece of dental floss or thin fishing line, slide it behind and then using a to and fro motion slowly proceed from one end to the other. You will cut through the backing without damaging the paintwork. Then use a mild solvent to remove the excess on the panel.
Make sure you mark where the badge sits first.
