Arrow Changing fog lights to LED DRLs

Changing fog lights to LED DRLs:

Looking for help from my fellow-BMW enthusiasts.

Loyal for 17 years to BMWs I went to the dark side as I could not resist a great
deal I found on my current 2009 SL550. No worries - my E46 is still in our garage
and coincidentally just tonight we broke 100,000 miles after 9+ years together.
BTW, my wife is thrilled that she ‘inherited’ the car from me 2 months ago ;- )

I liked everything about my car and was not thinking about doing any mods until
I saw a picture where someone successfully converted fog halogen lights to more
modern LED DRLs. My installation went without a hitch and I was very happy
with the overall look and execution. But we are not ‘home free’ just yet.

Since the wattage is lower on LEDs – as we expected, the lights are causing errors
on the dash board. Worse yet, they are not operational yet and are only giving
out some blinks and flashes every so often. My installers expected this and had
a few resistors ready to ‘fool the computer’ that the current is as it should be.
They tried 4 different values, but this only accomplished flickering and different
intervals. No steady-on light and of course – the errors are still on my dash.

I know that MB SLs are not cars that are modified extensively, so I am turning for
help from any car enthusiast that can shed some advice or suggest that I contact
someone (shop / company with accessories?) with knowledge and necessary parts.

Thanks in advance for any input...
(sorry this is not directly BMW related, but I was hoping that the same folks that
know how to overcome these challenges, would know it regardless the make & model)
