I have similar in my Tiguan, with the strips cut into sections of 9 white SMD bulbs. They give a nice light, but I think other colours look crap.
(They are actually the same colour, picture doesn't quite catch that).
They take a feed/ground from the front footwells, same as a mk5. If you don't have front footwells it is easy to buy a kit with the repair wire to take a feed from the CECM so it is all akin to a factory install.
