I guess you will get your answer from a dealer's parts dept (or a LR indy shop with a Microcat subscription...) I was not aware of a change - I only recall that the rear lamp assemblies did change when they removed the amber - but the GTR has no info on part numbers so it's definitely possible... If the light output is different in any way between the two, the insurance will have no choice but to pay for replacement of the right cluster as well. Then you can sell the old one on eBay. :twisted:
