Hi Mate,
i supply led lighting on this forum, they B7's will always get an error unless using a resistor wrapped around the holder but even then its not a fix.
for the side lights i can send you out a 9 led canbus which will not bring you any errors, for the plate lamp it will be best if you use the ones in my sig for a error free halogen ice whites.
any questions then please ask.
