Installing LED bar on roll pan

I installed a roll pan on my GMC and filled the taillamp pockets. The roll pan has one slot on each side for LED bars. I was told you can get an LED module to make a single led bar operate park, turn and brake lights. Any one know if this is possible and where I can get such a module?

I think I've seen them on eBay....

Go to Stylin Concepts and look it up in the newest book. I just recieved it and they had two bars or just one with the controls your looking for.
