Hey,
Sorry to resurrect this but are these http://www.kunzmann.de/shop/en/tuning-styling-vw-golf-5-v-led-rear-lights-set-candy-red-for-vw-golf-5-v.htm darker than the original OEM cherry red lights?
Thanks 
no apologies needed for resurrecting the main thread subject, it has went a bit sideways after all
I think these lights are just the standard European led rears, not available here and as far as I can tell will have to ALL be swapped over with regards to the fog and reverse light being on the wrong sides.
a few ways to do this as im sure you already know, there was a company on e-bay selling the very dark ones although they are modified by the company selling them, as far as I know this is the only company currently selling the dark ones but saying that they are very unhelpfull, not rude just very slow at replies and they do not have the dark ones for sale at the moment with no ideas as to the likelihood of more stock in the future
if you like I can give you the link to their web site and they currently run a shop on e-bay,, I think it is called aks tuning but I would need to check this if you are interested.
the link you supplied looks like the standard cherry shading as the item title suggests.
if anyone knows of anywhere that currently sells the darker versions of these lights, and if they have done the lights darker I would assume they have already swapped the interior bulbs for uk cars then let me know as I cant find anywhere and have only seen 1 car with these fitted
