Thank you for responding. I'm sure your assessment is correct. It's a pity that it is described as "LED Ambient Lighting" in every publication / review that I have seen, including the official brochure and in fact, the only place it is described as "ornamental", is in the User Guide supplied with the car. I think it would look quite stylish if it was a tad brighter.
Once again, thanks for your help.
