Finally installed the brake light last night. Took about two hours; and that was mainly just taking my time and cleaning up dirt & debris, and making the wiring tight. It was simple, but not because of any directions from the manufacture (holy hell would it kill a company to put together a step-by-step guide for a product that's been on the market this long and is this popular...)
Any way, beyond the great help on this forum I managed to find this video on Youtube that helped double check my assumptions and provided the last bit of advice I needed. If you are in this group; my many thanks for taking the time to make the guide.
My appreciation to
@BenBB ,
@Jhollowell , and
@RaptorActual for the advice to my specific questions. And thanks to
@4x4TruckLEDs.com for the fast shipping.
My early read on the lights: The whole kit is worth it. It's a solid, quality kit from end to end (aside from poor documentation). It has a great subtle but upgrade look to it. And they are BRIGHT. If you are on the fence; get off of it and buy them.
Pic is from across the Street around mid-day (full sun). You cannot look at them without seeing spots.
