The smoked rear LEDs are real eye candy. I sometimes go to the car at night and lock and unlock it (I just did it!) just to look at them. No other car, however exotic, has better looking tail lights IMO. 
Agreed, i've seen a couple in the flesh (though not on steel grey) and i'm so jealous! how much are my current lights worth? Hmm..........
I can't remember but
mike. will know. I've kept my originals to put back on when I sell the car. I'll sell the LEDs separately.
As a guess, you could sell your originals for £100 maximum for the pair. Not worth much now due to the LEDs being available, I am afraid.
