Hey DS, when you did your interior LED's, what/where did you buy them? I have tried several kits from Amazon/Ebay and have been very disappointed in the results. They are very dim in the interior when I open the door and half the time they don't even turn on. I have a set that I got for my Suburban on Amazon that was a kit for all 18 bulbs and those suckers are bright as hell but unfortunately that vehicle doesn't have the same lights as the Regal.
