When I first joined the GMTC there was a thread about how a guy converted his DRLs to LED and I think he put a resistor in the line to lower the voltage as I remember the voltage for the 4114 was too high and would burn them out shortly. I have done searches for this but can't find it.

Does anyone know how to do this. I want to convert 2007 Classic GMC 2500HD to LED.
