Check the voltage supplied to the DRL's. They are very dim which leads me to believe they are not getting a full 12V which is what would be required to fire off the LED's.
Wasn't there a post somewhere about needing to rewire the connector for the DRL's?

I searched and although there are a number of threads about conversion most of them are regular WK2's. Honestly, I don't know why the large DRL's are even powered on our trucks, they aren't powered as DRL's, just as annoying dim yellow lights when the headlights are on. I've contemplated removing them all together.
To make them work you will need to wire in a relay that will trigger on the supplied voltage and supply the LED with 12V.
