Well after a few months of deciding weather or not to change them I've upgraded the yellow DRL's for some canbus friendly white LED's. So far very pleased, changes the look of the car, took 10 mins to fit and no error messages! Time will tell on their reliability! I have gone for multi direction LED's (diodes in the front and side of the bulb) to make full use of the lamps reflectors to produce a even light from the lamp.
LED fitted on left with original bulb on right.
Night photo of both LED's fitted.
Bought from eBay and sent out next day
