Hi I have a MY2013 Freelander 2, SD4 GS.
It does not have map reading lights.
Is it possible to replace with interior lights from a better equipped model?

Yes,
option 1
message Dan at Duckworths for one of a HSE
Option 2
Get one from an upmarket Focus either new or S/H
.
Before buying new from Dan do a search on the forum for interior light upgrade / loadspace light as I've used the front lamp (that I removed), in the rear headlining by using a new ivory peritmeter light rim from the rear passenger light so you might want to order both parts from Dan. I've added photos as well and can reccomend the mod.
.
Kind regards from Fred
