Hi all,

I am just in the process of finishing the S6 LED DRL mod, and currently, I am getting the bulb failure warning - so I need a resistor.

As my LEDs replace a H7 55 watt lamp, I am trying to determine what size resistor I need, and whether i need to install in series or parallel.

It's been a while since I went to school, put I do remember V=IR and P=VI
That means I am looking for a 2.62 ohm resistor?

I have a couple of 2R7 50W resistors in the garage, and as they are set in a nice big heat sink, I would like to use them if possible... however, I think they might not be heavy enough, although the resistance is almost spot on.

Any advice would be appreciated!

Thanks.
