Yeah it's nice. Just feels unfinished.
I'm with you 100% I'd love it to light up, potentially you could run a lighting wire through slip ring to the leds in the wheel, as long as slip ring has extra cable it's possible, but for now I'm OK ish with it not lighting up, there isn't going to be much inside them switches so easy to find the lighting wire?
it might even be possible to parallel up a mk5 wheel electronics box (the one in the wheel itself) with the new wheel, i might give this a go first, doubling up on the lin bus cable, this is all just wishfull thinking as i don't want to pay out tones of money for more mk6 parts just for illumination
just thought of something else the power to the switches only comes on when ignition is on, use this to power the leds by a bit of poking around in the switches, this would obviously be lit all the time including day times but worth a go
