No LED DRL's yet and mine is a 40d, 2011MY. Still uses good old H8 lamps. I might fit the latest Philips LED8 DRL system as I expect the change to BMW LED DRLs like the E70 has will mean a complete light unit replacement as there are additional lighting modules to be fitted.

I have not found any LED replacements for the H8 that give anything like enough output - but then the E70 unit is 60LEDs.
