Im looking to find out how much and where could purchase a set of 2004 Bentley GT Continental rear lights.

But I have notice that there are two different types, there are ones that have the indicator flash up on the same as the brake light and theres one which has the indicator on a seperate indicator strip, I think this is becasue of higher spec.
If anyone could help me telling where I could get them or which model has the different lights it would be much appreciated.

Cheers
