Didn't know there was a W8 mirror. There is the W8 interior light which has the red LED downlights, I fitted one in my old Leon.
The new Leon and my Altea have the LEDs built into the Mirror, maybe some one has fitted one of these, does it have the auto-dimming function as well?
They light up the area round the gear lever. Looks good, gives a nice red glow to the area.
